1. Respiration is a chemical process that releases energy from food molecules in cells. Glucose is the main food molecule used and is broken down through a series of enzyme-controlled reactions.
2. Energy released during respiration is stored as chemical energy in ATP molecules. An enzyme joins phosphate to ADP to form ATP. When energy is needed, ATP is broken down by an enzyme into ADP and phosphate, releasing the stored chemical energy.
3. Aerobic respiration uses oxygen to fully break down glucose into carbon dioxide and water. This produces much more ATP than anaerobic respiration, which breaks down glucose without oxygen.

Please note that the example of Language/Dialectal Variation used in the Expository piece is "Jamaican Creole" and may not be a suitable example for other countries. Thank you.
his presentation is all about respiration occurring inside human bodies how they occur and is well explained via equations.hope students as well as instructors,teachers and professors would greatly benefit from this presentation.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Cells And Respiration
1.
2. Respiration is a chemical process in which energy is released from food molecules in cells. During respiration glucose is broken down in a series of reactions controlled by enzymes. The main food molecule used in cells is glucose. G

7. An enzyme joins an inorganic phosphate group (Pi) onto an A D P molecule to form an A T P molecule. A T P: contains a high level of chemical energy + Pi + energy Adenosine Pi Pi A D P Enzyme Adenosine Pi Pi Pi
8. You have to move muscles and need that stored energy. How is it released…? Enzyme + + Adenosine Pi Pi Pi Energy A D P Released for all cell activities Adenosine Pi Pi Pi A T P
9. This forms a continuous cycle of ATP-ADP-ATP… Storing and releasing energy when needed G glucose respiration A D P + Pi A T P Used in cell activities e.g muscle contraction
10.
11.
12.
13. Aero bic respiration is the process of release of energy from food in cells using oxygen. This happens in 2 stages: 1. Glycolysis 2. Breakdown of pyruvic acid
14.
15. 2. Breakdown of pyruvic acid Energy released by this stage allows a large quantity of A T P to be produced in the cells. Pyruvic acid + oxygen Enzyme controlled reactions Carbon dioxide + water
16. Total = 38 ATP molecules/ glucose + oxygen Carbon dioxide + water Overall A T P production during aer obic respiration: G Glucose Pyruvic acid 2 A D P + 2 Pi 2 A T P 36 A D P + 36 Pi 36 A T P
17.
18. Anaero bic respiration is the breakdown of glucose in cells without oxygen. This could happen in animal cells if not enough oxygen is getting to muscles during heavy exercise. Cells would have to change from: aer obic respiration to anaer obic respiration
19. As with aerobic respiration this happens in 2 stages: 1. Glycolysis (exactly the same as aerobic respiration) 2. Breakdown of pyruvic acid (but without oxygen) Pyruvic acid NO oxygen Enzyme controlled reactions Lactic Acid
20. Overall A T P production during anaer obic respiration in animals : G Glucose Pyruvic acid 2 A D P + 2 Pi 2 A T P (No oxygen) Lactic Acid No A T P molecules formed! Total = 2 ATP molecules/ glucose
21.
22. Just as in animals, glucose is only partially broken down in the absence of oxygen. Anaerobic conditions can occur when root cells of plants grow in muddy soil or there has been floods. Yeast cells are deprived of oxygen when used in brewing and bread-making.
23. As with anaerobic respiration in animals this happens in 2 stages: 1. Glycolysis (exactly the same as aerobic respiration) 2. Breakdown of pyruvic acid (but without oxygen) Pyruvic acid NO oxygen Enzyme controlled reactions Ethanol + Carbon dioxide (lost- reaction irreversible)
24. Overall A T P production during anaer obic respiration in plants and yeasts : Total = 2 ATP molecules/ glucose G Glucose Pyruvic acid 2 A D P + 2 Pi 2 A T P (No oxygen) Ethanol + CO2 No A T P molecules formed!
25.
26. Yeast - Unicellular fungus - Cell is dividing - Ferment sugars (used in brewing and bread making) These circles are formed when the cell divides. The new cell ‘ buds off’ and leaves a scar.
27. During ae robic respiration, yeast uses up glucose and oxygen and produces carbon dioxide and water. As oxygen is used up the yeast changes over to anae robic respiration and converts glucose to carbon dioxide and ethanol (alcohol).
