Final: Regulation of Cellular Respiration

Question 1

How do low and high energy molecules regulate cellular respiration?

Answer 1

low energy- stimulates/activates
high energy-inhibits respiration reactions

Question 2

Citrates impact on PFK

Answer 2

• example of negative feedback
• decreases PFK
• makes sense because: it occurs when glycolysis and pyruvate oxidation are working faster then the Kreb Cycle and reduces PFK because KREB cycle needs to catch up
