EOC REVIEW: CELLULAR PROCESSES- Cellular Respiration

Question 1

How does cellular respiration store ATP molecules?

Answer 1

Up to 32 ATP per glucose molecule are produced.

Question 2

What is the equation for cellular respiration?

Answer 2

C6H12O6 + 6O2 yields 6CO2 + 6H2O +ATP + Heat

Question 3

What are the three stages of cellular respiration?

Answer 3

Glycolysis; pyruvate oxidation and the citric acid cycle; oxidative phosphorylation (electron transport chain)
