1. Notes 7.1 – Glycolysis Cell Respiration Part 1 Page 131

2. Standards CLE 3210.3.3 Investigate the relationship between the processes of photosynthesis and cellular respiration. SPI 3210.3.3 Compare and contrast photosynthesis and cellular respiration in terms of energy transformation.

3. Identify the reactants and products of Glycolysis Evaluate situations when a cell must use anaerobic vs. aerobic respiration Summarize the major events in Glycolysis

4. Find a Partner

5. Tell your partner what making a bond means in terms of energy?

6. Tell your partner what breaking a bond means in terms of energy?

7. With your Partner: Look up the definition of “cellular respiration” Determine if both plant and animal cells can perform cellular respiration. Give evidence to support your answer.

8. Electron Transport Chain Overview of Cell RespirationCell Respiration Equation: Three Main Parts: - Glycolysis – Happens in cytosol Krebs Cycle– Happens in mitochondria C 6 H 12 O 6 + O 2  CO 2 + H 2 O + ATP (energy)

9. Glycolysis Reactants: Products: Glucose, 2 ATP, NAD+ Pyruvate – moves to Kreb Cycle H 2 O – becomes part of cytosol 4 ATP – used by cell NADH – moves to electron transport chain

10. With your partner Think about the following question: If Glycolysis makes 2 molecules of water, why do we need to drink water?

11. What if I told you that if you put 50 cents into a vending machine, it would give you a dollar? Would you put in 50 cents? Why? What would be your profit? Profit (Net gain) = amount gained - amount invested

12. _____ ATP are required to start Glycolysis _____ ATP are produced ______ = the net gain of energy produced by Glycolysis 2 4 2

13. What happens to Pyruvate? Two possible paths: Pyruvate Aerobic Respiration (mitochondria) Fermentation (cytosol) Lots of ATP Some ATP

14. With your Partner Look in the book and list 2 situations where fermentation is used instead of aerobic respiration.
