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. 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.

6. Overview of Cell Respiration Equation: Two Main Parts: Glycolysis (anaerobic) – Happens in cytosol Aerobic respiration – Happens in mitochondria C 6 H 12 O 6 + O 2  CO 2 + H 2 O + ATP (energy)

7. 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

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

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

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

11. With your Partner Give some situations where fermentation is used instead of aerobic respiration.
