Glycolysis occurs in two stages: (1) an energy investment phase where ATP is used to phosphorylate intermediates, and (2) an energy generation phase where a net of 2 ATP and 2 NADH are produced per glucose molecule. The 10 steps of glycolysis ultimately convert glucose to pyruvate, with a net production of 2 ATP per glucose under anaerobic conditions or a net of 2 ATP plus the potential energy of 2 NADH under aerobic conditions. Glycolysis is regulated by hormones and substrates to balance energy production with the body's nutritional state.

Glycolysis is the pathway for oxidation of glucose to pyruvate. It occurs in the cytosol and consists of three phases: priming, splitting, and oxidative. In the priming phase, glucose is converted to fructose-1,6-bisphosphate using two ATP molecules. The splitting phase produces two molecules of glyceraldehyde-3-phosphate. Oxidation of these yields two pyruvate, two NADH, and generates a net of two ATP per glucose under anaerobic conditions or 38 ATP under aerobic respiration. Key regulatory enzymes are phosphofructokinase-1 and pyruvate kinase.
Cellular respiration involves three main stages: glycolysis, the Krebs cycle, and the electron transport chain. [1] Glycolysis takes place in the cytosol and involves the breakdown of glucose into pyruvate, producing a small amount of ATP. [2] Pyruvate then enters the mitochondrion, where it is further oxidized in the Krebs cycle. [3] Electrons are transferred in the electron transport chain to produce most of the cell's ATP through oxidative phosphorylation.
Glycolysis is the breakdown of glucose to pyruvate or lactate with production of a small amount of ATP. It occurs in the cytoplasm and consists of 10 steps, including phosphorylation of glucose, cleavage of fructose-6-phosphate, and conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. Aerobic glycolysis produces pyruvate and 8 ATP, while anaerobic glycolysis produces lactate and 2 ATP. Glycolysis is the primary source of energy in red blood cells and during strenuous exercise when oxygen is limited.

1) Glycolysis is the first pathway of glucose metabolism that breaks glucose down into pyruvate, producing a small amount of ATP.
2) Glycolysis involves several phosphorylation and oxidation-reduction reactions regulated by factors like insulin, ATP levels, and fructose 2,6-bisphosphate.
3) The breakdown of glucose via glycolysis is critical for producing energy in red blood cells and some microbes that lack mitochondria.
This document discusses carbohydrate metabolism and glycolysis. It begins by classifying carbohydrate metabolism into glycolysis, the Krebs cycle, the hexose monophosphate shunt, glycogenesis, glycogenolysis, and gluconeogenesis. It then provides details on glycolysis, including that it converts glucose to pyruvate or lactate, involving 10 reactions in 3 stages. Key enzymes and reactions in each stage are described. The document also discusses regulation of glycolysis and differences between hexokinase and glucokinase.
Glycolysis is a catabolic pathway that breaks down glucose into pyruvate, generating ATP and NADH. It occurs in two phases:
1. The energy investment phase involves phosphorylation of intermediates using ATP as five intermediates are formed.
2. The energy generation phase yields ATP and NADH as the remaining intermediates are formed, with a net production of two ATP and two NADH per glucose molecule.
Glycolysis is tightly regulated at three irreversible steps by enzymes such as hexokinase, phosphofructokinase, and pyruvate kinase. It allows for ATP production under both aerobic and anaerobic conditions.

Metabolism is the network of chemical reactions that take place in living cells. It performs four main functions: obtaining energy, converting nutrients into macromolecules, assembling macromolecules, and degrading macromolecules. Metabolic pathways can be catabolic, anabolic, or amphibolic. Glycolysis converts glucose into pyruvate, generating a small amount of ATP. Pyruvate then undergoes oxidative decarboxylation to form acetyl-CoA, the entry point into the citric acid cycle. Diseases can impair glycolysis through deficiencies in enzymes like pyruvate kinase or disorders that cause lactic acidosis.

Glycolysis is the metabolic pathway that converts glucose into pyruvate and produces a small amount of ATP. It occurs in the cytoplasm of cells and can function aerobically or anaerobically. During aerobic glycolysis, pyruvate is further oxidized to produce more ATP. During anaerobic glycolysis, pyruvate is converted to lactate, producing less ATP. The citric acid cycle is a series of chemical reactions in the mitochondria that completes the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins to produce carbon dioxide, water, and ATP through oxidative phosphorylation. It is also known as the Krebs cycle or TCA cycle. It is a key step
Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH through substrate-level phosphorylation. It occurs in the cytosol through 10 steps, two of which generate ATP. The pathway ends with pyruvate which can then undergo fermentation or enter the citric acid cycle. Glycolysis is regulated by feedback inhibition and substrate availability. Gluconeogenesis is the reverse of glycolysis and produces glucose through anabolic reactions in the liver. Glycogen synthesis and breakdown allow for storage and mobilization of glucose as glycogen through glycogenesis and glycogenolysis respectively.
Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products. Though often maligned in trendy diets, carbohydrates — one of the basic food groups — are important to a healthy diet.
Glycolysis and gluconeogenesis are two important metabolic pathways. Glycolysis converts glucose into pyruvate and generates a small amount of ATP. Gluconeogenesis converts non-carbohydrate sources into glucose, which is important for supplying glucose to tissues between meals. Deficiencies in enzymes in these pathways can cause diseases like hemolytic anemia or hypoglycemia.
To understand how the glycolytic pathway is converts glucose to pyruvate.
To understand conservation of chemical potential energy in the form of ATP and NADH.
To learn the intermediates, enzyme, and cofactors of the glycolytic pathway.
The document summarizes two types of fermentation: alcoholic fermentation and lactic acid fermentation. In alcoholic fermentation, yeast and microorganisms ferment glucose to ethanol and CO2 through glycolysis and subsequent conversion of pyruvate to acetaldehyde and ethanol. In lactic acid fermentation, when tissues cannot be supplied with oxygen, NAD+ is regenerated through the reduction of pyruvate to lactic acid by lactate dehydrogenase. Lactic acid fermentation allows extraction of some energy from glucose in the form of ATP.
The prime cause and treatment of cancer somayeh zaminpira - sorush niknamianbanafsheh61
This meta-analysis research has gone through more than 200 studies from 1934 to 2016 to find the differences and similarities in cancer cells, mostly the cause. The most important difference between normal cells and cancer cells is how they respire. Normal cells use the sophisticated process of respiration to efficiently turn any kind of nutrient that is fat, carbohydrate or protein into high amounts of energy in the form of ATP. This process requires oxygen and breaks food down completely into harmless carbon dioxide and water. Cancer cells use a primitive process of fermentation to inefficiently turn either glucose from carbohydrates or the amino acid glutamine from protein into small quantities of energy in the form of ATP. This process does not require oxygen, and only partially breaks down food molecules into lactic acid and ammonia, which are toxic waste products. The most important result is that fatty acids or better told fats cannot be fermented by cells. This research mentions the role of ROS and inflammation in causing mitochondrial damage and answers the most important questions behind cancer cause and mentions some beneficial methods in preventing and treatment of cancer.
The document discusses glycolysis and the citric acid cycle. Glycolysis involves 10 steps that break down glucose and generate a small amount of ATP without oxygen. The citric acid cycle is a series of chemical reactions in the mitochondria that further oxidizes pyruvate from glycolysis to extract more chemical energy. It involves 8 steps that produce carbon dioxide, NADH, and FADH2 to fuel the electron transport chain for oxidative phosphorylation to generate large amounts of ATP. Both pathways are tightly regulated and provide precursors for other biological processes.

Your Skill Boost Masterclass: Strategies for Effective Upskilling
glycolysis-1.pptx
1. Two phases of glycolysis
The conversion of glucose to pyruvate occurs in
two stages .The first five reactions of glycolysis
correspond to an energy investment phase in
which the phosphorylated forms of
intermediates are synthesized at the expense of
ATP.
The subsequent reactions of glycolysis
constitute an energy generation phase in which
a net of two molecules of ATP and 2 NADH are
formed by substrate-level phosphorylation per
glucose molecule metabolized.
2.
3.
4. 1. Phosphorylation of glucose
Phosphorylated sugar molecules do not readily
penetrate cell membranes, because there are no
specific transmembrane carriers for these
compounds, and because they are too polar to
diffuse through the lipid core of membranes.
Mammals have several isozymes of the enzyme
hexokinase that catalyze the phosphorylation of
glucose to glucose 6-phosphate.
Hexokinase has broad substrate specificity and is
able to phosphorylate several hexoses in addition
to glucose.
5.
6. 2. Isomerization of glucose 6-phosphate
The isomerization of glucose 6-phosphate to
fructose 6-phosphate is catalyzed by phospho
glucose isomerase
3. Phosphorylation of fructose 6-phosphate
The irreversible phosphorylation reaction
catalyzed by phospho - fructokinase-1 (PFK-1)
is the most important control point and the
rate-limiting and committed step of glycolysis
PFK-1 is controlled by the available
concentrations of the substrates ATP and
fructose 6- phosphate.
7.
8.
9. 4. Cleavage of fructose 1,6-bisphosphate
Aldolase cleaves fructose 1,6-bisphosphate to
dihydroxy acetone phosphate and glyceraldehyde
3-phosphate
5. Isomerization of dihydroxyacetone phosphate
Triose phosphate isomerase interconverts
dihydroxyacetone phosphate and glyceraldehyde
3-phosphate. Dihydroxy - acetone phosphate
must be isomerized to glyceraldehyde 3-
phosphate for further metabolism by the
glycolytic pathway. This isomerization results in
the net production of two molecules of glycer -
aldehyde 3-phosphate from the cleavage
products of fructose 1,6- bisphosphate.
10. 6. Oxidation of glyceraldehyde 3-phosphate
The conversion of glyceraldehyde 3-phosphate to
1,3-bisphosphoglycerate by glyceraldehyde 3-
phosphate dehydrogenase is the first oxidation-
reduction reaction of glycolysis. Because there is
only a limited amount of NAD+ in the cell, the
NADH formed by this reaction must be reoxidized
to NAD+ for glycolysis to continue. Two major
mechanisms for oxidizing NADH are:
1) the NADH-linked conversion of pyruvate to
lactate (anaerobic)
2) oxidation of NADH via the respiratory chain
(aerobic)
11. 7. Synthesis of 1,3-bisphosphoglycerate (1,3-
BPG):
The oxidation of the aldehyde group of
glyceraldehyde 3-phosphate to a carboxyl
group is coupled to the attachment of Pi to
the carboxyl group. The high-energy
phosphate group at carbon 1 of 1,3-BPG
conserves much of the free energy produced
by the oxidation of glyceraldehyde 3-
phosphate. The energy of this high-energy
phosphate drives the synthesis of ATP in the
next reaction of glycolysis.
12.
13. Synthesis of 2,3-bisphosphoglycerate (2,3-
BPG) in red blood cells:
Some of the 1,3-BPG is converted to 2,3-BPG
by the action of bisphosphoglycerate mutase
(see Figure). 2,3-BPG, which is found in only
trace amounts in most cells, is present at high
concentration in red blood cells (increases O2
delivery) .2,3-BPG is hydrolyzed by a
phosphatase to 3-phosphoglycerate, which is
also an intermediate in glycolysis .
14. 8. Synthesis of 3-phosphoglycerate producing
ATP
When 1,3-BPG is converted to 3-
phosphoglycerate, the high-energy phosphate
group of 1,3-BPG is used to synthesize ATP
from ADP. This reaction is catalyzed by
phosphoglycerate kinase.Because two
molecules of 1,3-BPG are formed from each
glucose molecule, this kinase reaction
replaces the two ATP molecules consumed by
the earlier formation of glucose 6-phosphate
and fructose 1,6-bisphosphate.
15. Shift of the phosphate group from carbon 3
to carbon 2
The shift of the phosphate group from carbon
3 to carbon 2 of phosphoglycerate by
phosphoglycerate mutase is freely reversible
16. 9. Dehydration of 2-phosphoglycerate
The dehydration of 2-phosphoglycerate by
enolase redistributes the energy within the 2-
phosphoglycerate molecule, resulting in the
formation of phosphoenolpyruvate (PEP),
which contains a high energy enol phosphate.
10. Formation of pyruvate producing ATP
The conversion of PEP to pyruvate is catalyzed
by pyruvate kinase. The equilibrium of the
pyruvate kinase reaction favors the formation
of ATP
17.
18. Reduction of pyruvate to lactate
Lactate, formed by the action of lactate
dehydrogenase, is the final product of
anaerobic glycolysis in eukaryotic cells.
The formation of lactate is the major fate for
pyruvate in lens and cornea of the eye, kidney
medulla, testes, leukocytes and red blood
cells, because these are all poorly vascularized
and/or lack mitochondria.
19.
20. Energy yield from glycolysis
• Despite production of ATP in glycolysis, the
end product still contains most of energy
contained in glucose. The TCA cycle I required
to release that energy completely.
• 1. Anaerobic glycolysis: two molecules of ATP
are generated for each molecule of glucose
converted to two molecules of lactate. There
is no net production or consumption of NADH.
21. 2. Aerobic glycolysis
• The direct consumption and formation of ATP is
the same as in anaerobic glycolysis (that is a net
gain of two ATP per molecule of glucose). Two
molecules of NADH are also produced per
molecule of glucose. Ongoing aerobic glycolysis
requires the oxidation of most of this NADH by
the electron transport chain, producing
approximately three ATP for each NADH molecule
entering the chain (NADH cannot cross the inner
mitochondrial membrane, and substrate shuttle
are required.
22. Energy from glycolysis
• ATP consumed 2 moles
• ATP produced direct 4 moles
• ATP indirect (NADH/H) 6 moles
• Net ATPs = 10-2= 8 moles
• If anaerobic glycolysis 2 moles
23. Lactate formation in muscle:
In exercising skeletal muscle, NADH
production exceeds the oxidative capacity of
the respiratory chain. This results in an
elevated NADH/NAD+ ratio, favoring reduction
of pyruvate to lactate. Therefore, during
intense exercise, lactate accumulates in
muscle, causing a drop in the intracellular pH,
potentially resulting in cramps.
24. Lactic acidosis:
Elevated concentrations of lactate in the
plasma, termed lactic acidosis, occur when
there is a collapse of the circulatory system,
such as in myocardial infarction, pulmonary
embolism, and uncontrolled hemorrhage, or
when an individual is in shock. The failure to
bring adequate amounts of oxygen to the
tissues results in impaired oxidative
phosphorylation and decreased ATP synthesis.
To survive, the cells use anaerobic glycolysis as
a backup system for generating ATP, producing
lactic acid as the end product.
25. REGULATION OF GLYCOLYSIS
During the well-fed state:
Decreased levels of glucagon and elevated levels
of insulin, such as occur following a carbohydrate-
rich meal, cause an increase in fructose 2,6-
bisphosphate and, thus, in the rate of glycolysis in
the Fructose 2,6-bisphosphate, therefore, acts as
an intracellular signal, indicating that glucose is
abundant.
During starvation:
Elevated levels of glucagon and low levels of
insulin, such as occur during fasting decrease the
intracellular concentration of hepatic fructose 2,6-
bisphosphate. This results in a decrease in the
overall rate of glycolysis and an increase in
gluconeogenesis.
