Question

Ch 9

1.    Know the chemical reaction of cellular respiration

2.    Know like

the back of your hand about redox reactions and describe what is being oxidized and reduced in cellular respiration (OIL RIG: Oxidation is Loss; Reduction is Gain in electrons)

3.    Now that you know about redox reactions and how we utilize food to make ATP, tell me why pound for pound fats hold more potential energy than sugars.

4.    Describe how Nicotinamide (NAD) serves as an electron carrier. NAD+/NADH which is in reduced and which is in oxidized form? 

5.    Know the 10 steps of glycolysis, the enzymes involved and what they do. 

6.    Know when and where substrate level phosphorylation makes ATP during cell respiration

7.    What happens to pyruvate as it enters the mitochondria? 

8.    What is the overall function of the citric acid cycle? What is being made? Why is it a cycle? 

9.    What happens to all the electrons that are being stripped from glucose? Where to they go? How do they facilitate the replenishment of ATP? 

10. What is oxidative phosphorylation and chemiosmosis? Where is this occurring? 

11. Describe why the structure of the inner mitochondrial membrane is so crucial to its function

12. Think about the evolutionary significance of glycolysis in relation to where it occurs in the cell. 

13. What is the difference between fermentation, aerobic and anaerobic respiration?
