Energy systems
Energy is the ability to do work and is transferred or converted between different forms. ATP provides energy for physiological processes through the breakdown of phosphate bonds. There are three main energy systems in the body: 1) ATP-PCr system provides short bursts of energy through phosphate transfer from creatine phosphate to ATP. 2) Lactic acid system provides moderate energy through anaerobic glycolysis but produces lactic acid. 3) Aerobic system provides sustained energy through oxygen-based breakdown of glucose and fats, producing water and carbon dioxide.

Energy is required for sustained physical and mental activity. The body gets energy from food, which is converted into ATP through various energy systems. There are three main energy systems: 1) ATP-PC system provides energy for up to 10 seconds through ATP and phosphocreatine. 2) Lactic acid system provides energy for 10-30 seconds by breaking down glucose to make ATP and lactic acid. 3) Aerobic system provides sustained energy over minutes by breaking down glucose and fatty acids with oxygen to make ATP through cellular respiration. These systems provide energy for different durations and intensities of exercise.

Energy is required for sustained physical and mental activity and is obtained from foods and drinks through digestion. Adenosine triphosphate (ATP) is the primary energy carrier in living organisms and is broken down through hydrolysis to provide energy for growth and life. There are three energy systems - ATP-PC, lactic acid, and aerobic - that are used depending on the oxygen availability and energy demands, with the ATP-PC system providing immediate energy through phosphocreatine breakdown, the lactic acid system producing 2-3 ATP molecules anaerobically, and the aerobic system producing 38-129 ATP molecules with oxygen. A 100m sprint predominantly uses the ATP-PC system while a 1500m race uses all

The document discusses the three main energy systems in the body:
1. ATP-PC system - Produces a constant flow of ATP for daily activity and fuels metabolism. Important for short bursts of energy.
2. Lactic acid system - Fuels high intensity exercise for short periods through anaerobic respiration, but builds up lactic acid.
3. Aerobic system - Most complex system that produces the most ATP for longest periods through oxygen, good for long distance exercise and weight loss. Each system fuels different aspects of movement and lifestyle.

ENERGY SOURCE AND THERMAL CHANGES IN MUSCLE CONTRACTION
This document discusses the energy sources and thermal changes that occur during muscle contraction. It notes that ATP is the immediate source of energy for muscle contraction, obtained initially from the hydrolysis of phosphocreatine and later through glycolysis and oxidative metabolism. Intense exercise leads to an oxygen deficit that is paid back after as oxygen debt. Muscle contraction results in the production of resting heat, initial heat during contraction, recovery heat after contraction, and relaxation heat. The efficiency of muscle contraction depends on whether it is an isotonic or isometric contraction.

Exercise Physiology
Muscle contraction occurs when motor neurons stimulate muscle fibers, causing calcium release from the sarcoplasmic reticulum. The calcium binds to troponin, exposing actin binding sites for myosin. Cross bridges form between actin and myosin, pulling the thin filaments towards the center of the sarcomere and causing muscle shortening. ATP provides the energy for cross bridge cycling through its hydrolysis during contraction. The three main energy systems - phosphagen, glycolysis and aerobic - supply ATP in varying amounts depending on the intensity and duration of muscle activity.

Biology 8.3
The document describes the key components and reactions of photosynthesis. It defines thylakoids, photosystems, and the stroma as parts of the chloroplast involved in photosynthesis. It explains that the light-dependent reactions use energy from light to produce ATP and NADPH by transferring electrons from chlorophyll to molecules like NADP+. The Calvin cycle then uses energy from ATP and NADPH to build sugars and other high-energy compounds.
Respiration
Cell respiration is the controlled release of energy from organic compounds like glucose to form ATP. There are two types of respiration: aerobic respiration, which uses oxygen to produce more ATP, and anaerobic respiration, which produces less ATP without oxygen. Aerobic respiration involves glycolysis in the cytoplasm, the Krebs cycle in the mitochondria, and the electron transport chain in the inner mitochondrial membrane, which produces the most ATP.
Austin baker assignment 1 energy systems
The document discusses three energy systems - ATP-PCr, glycolytic, and oxidative systems - that the body uses to produce ATP for muscle contraction and energy. The ATP-PCr system uses ATP and phosphocreatine to immediately resynthesize ATP for about 10 seconds of intense exercise. The glycolytic system breaks down glucose to produce energy, mainly through lactic acid production, for 30-45 seconds of activity. The oxidative system uses slow glycolysis, the Krebs cycle, and electron transport chain, along with beta oxidation of fats, to aerobically produce most of the body's energy through oxygen for sustained lower-intensity exercise lasting over 90 seconds.

Aerobic system
The document discusses the aerobic system of energy production for exercise. It involves 3 main stages: 1) Glycolysis, 2) Krebs cycle, and 3) Electron transport chain. During these stages, glycogen and fats are broken down to produce ATP through oxidative phosphorylation. The aerobic system is efficient and can sustain low to moderate exercise for long periods due to high oxygen availability and energy yield.
Muscle Energy Systems
Muscle metabolism relies on ATP as the direct source of energy for contraction. ATP stores are quickly depleted after 4-6 seconds of contraction and must be regenerated through creatine phosphate interaction, anaerobic glycolysis, and aerobic respiration. When muscle activity reaches 70% of maximum, oxygen delivery is impaired and lactic acid builds up, diffusing into the bloodstream. Muscle fatigue occurs when ATP production cannot keep up with demand, leading to relative ATP deficit, contractures, and lactic acid accumulation.
Energy systems
The document discusses the three main energy systems - ATP-PC system, lactic acid system, and aerobic system. It provides examples of how each system is used in different sporting events like sprinting, long distance running, and field events. The ATP-PC system provides energy over seconds, the lactic acid system over minutes, and the aerobic system provides virtually unlimited energy through oxygen. The first law of thermodynamics states that energy cannot be created or destroyed, only changed from one form to another.
Energy systems
Energy is the ability to do work and comes in different forms. ATP is a high-energy compound that provides energy for cellular processes.

Each system is used in different sports and activities depending on their intensity and duration requirements.

Energy is the ability to do work and comes in different forms. The human body gets energy from breaking down food sources like carbohydrates, fats, and proteins. The body has three energy systems - phosphocreatine, lactic acid, and aerobic - that produce ATP for muscle contraction and movement. The phosphocreatine system provides fast energy for bursts of intense activity up to 10 seconds. The lactic acid system takes over for moderate intensity exercise up to 3 minutes. The aerobic system produces sustained energy for low to moderate intensity activities lasting over 3 minutes by using oxygen.
Energy systems anatomy
This document discusses various energy systems used in sports. It explains that ATP is used for short bursts of energy like sprinting, while phosphocreatine provides energy for 12 seconds. The lactic acid system operates for 2 minutes during intense exercise. The aerobic system sustains energy for over 2 hours through oxygen. Different events utilize different systems - sprints rely on ATP and phosphocreatine, while long distance events depend more on the aerobic system.

This document discusses the three main energy systems in the human body - ATP-CP, anaerobic lactic, and aerobic. ATP-CP provides energy for bursts of high intensity activity lasting 10 seconds or less without oxygen. Anaerobic lactic supplies energy for medium intensity activity from 10 seconds to 2 minutes and produces lactic acid. Aerobic provides energy for low intensity activity lasting 2 minutes or more with oxygen. While each system dominates at different activity levels, all three systems typically work together during physical activity and sports.

This document discusses sources of energy during rest and exercise. It explains that cells use ATP as their main source of energy, which is produced through breaking down nutrients like carbohydrates, fats, and proteins. There are three main energy systems: phosphagen, anaerobic glycolysis, and aerobic. Phosphagen provides immediate energy for bursts of activity up to 10 seconds. Anaerobic glycolysis fuels moderate intensity exercise up to 2 minutes through lactate production. Aerobic oxidation sustains long duration activities by producing large amounts of ATP from oxygen. Recovery from exercise involves paying back oxygen debt and replenishing energy stores through lactate clearance and glycogen resynthesis.

The lactic acid system provides energy for 30 seconds to 3 minutes through anaerobic breakdown of glucose. The aerobic system provides sustained energy through aerobic respiration but takes longer to produce ATP. Examples are given of sports that rely on each system, such as basketball using ATP-PC and lactic acid and distance running using aerobic.
Energy systems
Adenosine triphosphate (ATP) is an organic chemical that transfers energy within cells. ATP is often called the "molecular unit of currency" of intracellular energy transfer. Energy cannot be created or destroyed, only transferred between forms. It is a property of objects that can be transferred or converted. Thermodynamics demonstrates how energy from the sun is transferred through grass, then a cow, and ultimately to a human consuming the cow. Muscular contraction, digestion, and tissue repair all require energy in the form of ATP.
Organigram
The document summarizes the different energy systems the human body uses to produce energy for physical activity. It discusses the ATP-CP, anaerobic glycolysis, and aerobic energy systems. The ATP-CP system provides energy for bursts of intense activity lasting 2-3 seconds. The anaerobic glycolysis system lasts 2-3 minutes and produces energy without oxygen through breaking down glycogen. The aerobic system provides sustained energy for longer duration activities through oxygen-dependent breakdown of carbohydrates and fats.

L10 Energy Systems
1. Cells produce energy in the form of ATP through breaking down nutrients like carbohydrates, fats, and proteins. ATP is constantly being used and replenished through different energy systems.
2. There are three main energy systems: the ATP-CP system which provides energy for up to 10 seconds; anaerobic glycolysis which takes over for 1-3 minutes; and the aerobic system which sustains energy for over 3 minutes through oxidative phosphorylation.
3. The aerobic system fully breaks down glucose or fatty acids to produce much more ATP than the other systems, using oxygen to facilitate reactions in the mitochondria and electron transport chain. This makes the aerobic system well-suited for longer,
L10 Energy Systems
1. Cells produce energy in the form of ATP through various energy systems, including the ATP-CP system, anaerobic glycolysis, and the aerobic system.
2. The ATP-CP system provides energy for 2-10 seconds by resynthesizing ATP from creatine phosphate. Anaerobic glycolysis produces energy without oxygen for 1-3 minutes by breaking down carbohydrates.
3. The aerobic system provides sustained energy over 3 minutes by oxidizing carbohydrates and fat through the mitochondria and electron transport chain to produce large amounts of ATP. Together these systems power human movement.
Energy
Energy is a property that can be transferred or converted into different forms. The sun provides energy for life on Earth through photosynthesis in plants. ATP is produced through cellular respiration and stores energy that organisms use for functions like movement. There are three main energy systems: immediate/phosphocreatine uses stored creatine phosphate and lasts seconds; lactic acid/short-term breaks down glycogen and glucose anaerobically and lasts minutes; aerobic/long-term uses oxygen to break down glucose and fatty acids aerobically, lasting over a minute. Each system powers different durations and intensities of exercise and sport.
Energy systems (p7%2c m4%2c d2 ) for steve
The document discusses the three energy systems - phosphagen, anaerobic glycolysis, and aerobic respiration - that provide energy for physical activity. The phosphagen system uses creatine phosphate to rapidly generate ATP for bursts of intense activity up to 30 seconds. Anaerobic glycolysis produces ATP without oxygen through glucose breakdown, fueling moderate intensity activity for up to 3 minutes. Aerobic respiration uses oxygen to slowly but sustainably produce ATP from carbohydrates and fats, fueling long duration lower intensity exercise. The document provides examples of which systems predominate in different sporting events.
Energy systems (p7 m4 d2)
The document discusses energy systems in the human body. It defines energy and explains that it comes mainly from the sun and food. There are three main energy systems: the phosphagen system provides a rapid burst of energy for up to 30 seconds; the lactic acid system provides energy for 30 seconds to 3 minutes; and the aerobic system provides sustained energy through oxygen but more slowly. These systems work together to fuel different intensities and durations of physical activity. Examples are given of how each system is used in 100m and 1500m races.

Indian Premier League (IPL) ---2024.pptx
The Indian Premier League (IPL) is one of the most prominent and lucrative Twenty20 (T20) cricket leagues in the world. Since its inception in 2008, the IPL has revolutionized the landscape of cricket by blending sports, entertainment, and commerce. This summary provides an overview of the IPL's history, structure, notable performances, controversies, and its impact on cricket and beyond.
History and Formation
The IPL was launched by the Board of Control for Cricket in India (BCCI) in 2008, inspired by the success of domestic T20 leagues like the English T20 Cup and the now-defunct Indian Cricket League (ICL). Lalit Modi, the then Vice-President of BCCI, played a crucial role in conceptualizing and launching the league. The inaugural season kicked off in April 2008 with eight franchises representing different cities in India.
Structure and Format
The IPL follows a franchise-based model, where teams are owned by a mix of corporations, Bollywood stars, and other high-profile individuals. The league originally started with eight teams, although the number has fluctuated over the years due to various reasons including expansions and terminations. As of the latest seasons, the IPL features ten teams.
The tournament format includes a double round-robin stage, where each team plays the others twice, followed by playoffs. The top four teams from the round-robin stage qualify for the playoffs, which consist of two qualifiers, an eliminator, and the final. This format ensures a highly competitive and engaging tournament, culminating in a grand finale to crown the champion.
Teams and Their Evolution
The founding teams of the IPL were:
Chennai Super Kings (CSK)
Delhi Daredevils (now Delhi Capitals)
Kings XI Punjab (now Punjab Kings)
Kolkata Knight Riders (KKR)
Mumbai Indians (MI)
Rajasthan Royals (RR)
Royal Challengers Bangalore (RCB)
Deccan Chargers (now defunct, replaced by Sunrisers Hyderabad)
Over the years, the league has seen new teams such as Pune Warriors India, Kochi Tuskers Kerala, Gujarat Lions, and Rising Pune Supergiant. The most recent additions are the Gujarat Titans and Lucknow Super Giants, introduced in the 2022 season.
Iconic Players and Performances
The IPL has attracted the best talent from around the world, with numerous iconic players making significant contributions. Some of the standout performers include:
Sachin Tendulkar (MI): The "Little Master" brought his legendary status to the IPL, winning the Orange Cap (top run-scorer) in 2010.
Chris Gayle (RCB, KXIP): Known for his explosive batting, Gayle holds the record for the highest individual score in an IPL match (175*).
MS Dhoni (CSK): Dhoni's leadership has been instrumental in CSK's success, leading them to multiple titles.
AB de Villiers (RCB): Renowned for his innovative stroke play, de Villiers has been a consistent match-winner.
Virat Kohli (RCB): The highest run-scorer in IPL history, Kohli's batting prowess is unmatched.

- 1. Energy Systems BY ROSIE FAULKNER
- 2. What is energy and ATP? Energy is a property objects which can be transferred to other objects or converted into different forms (Wikipedia 2016). The ‘ability of a system to perform work’ is a common description, but is misleading because energy is not available to do work (Wikipedia 2016) ATP= adenosine triphosphate, this is energy currency of the cell it is usually the direct source of chemical energy for any energy- requiring process in the cell.
- 3. Energy on this planet is provided by the sun Heat + light energy The first law of thermodynamics in energy is neither created or destroyed its transformed from one form to another, for example you have heat and light coming from the sun and you have chemical energy in the grass
- 4. Why do we need energy? Muscular contractions and movement- the source of energy that is used to power the movement of contraction in working muscles is ATP. Circulation- Better blood circulation can benefit the heart and other muscles in the body and the arteries. Better blood circulations means more oxygen in the body. Transmissions of nerve impulses- the nerve impulses needs ATP to stimulate the transmissions. Digestion of foods- the nutrients in food gives the body’s cells the energy and other substances they need to operate. Repairing an replacing tissues- it requires ATP
- 5. Phosphocreatine Phosphocreatine (PC) energy system provides immediate energy through the breakdown of these stored high energy phosphates. Phosphocreatine is known as creatine phosphate. It is stored in muscle cells and used as a fuel to create or 'synthesize' ATP. Aerobic means with oxygen and anaerobic means without oxygen. This energy system is only used for a short amount of time ( about 10 seconds) at maximum intensity. Creatine Phosphate and ADP combine together to create ATP+Creatine Recovery time- 8-10 minutes
- 6. Lactic acid system • Lactic acid is the short-term energy system. • To meet energy requirements of higher intensity over a longer period of time, such as during a 400-metre race. • ATP can be made by the breakdown of glucose and glycogen. • 60-90 seconds of maximal work • Glucose --> 2ATP + 2 lactic acid + heat Glycogen --> 3 ATP + 2 lactic acid + heat • The process of lactic acid recovery can take anywhere between 30 and 60 min. • Recovery time- 10-20 minutes
- 7. Aerobic energy system • The aerobic system is the long- term energy system • This energy system produces a lot more ATP than either of the other energy systems, but it produces it much more slowly. • This system produces carbon dioxide and water • Glucose + oxygen --> 38 ATP + carbon dioxide + water + heat Fatty acids + oxygen --> 129 ATP + carbon dioxide + water + heat • Recovery time- 5- 8 minutes
