Unit 3 Aerbic regulation

Question 1

What are the main inhibitors?
1.
2.
3.
4.

Answer 1

1. phosphofructosekinase
   -Allosteric
   -glycolysis
2. ATP
   -feedback

3.Citrate
-feedback
-kreb cycle
-synchronizes glycolsis and krebs

4. NADH
   -pyruvate oxidation

Question 2

Why is regulation nessesary?

Answer 2

for efficency
-no waste ATP
-no too little ATP

maintain ATP : ADP ratio

Question 3

what are statagey points?

Answer 3

speific point inhibitors target

Question 4

ATP vs AMP

Answer 4

ATP = inhibitor
AMP = stimulent

Question 5

Substrate level phosphoration vs oxidative phoshphoration

Answer 5

Substrate level phosphoration: Direct ADP –> ATP
-glycolysis
-krebs

oxidative phoshphoration: indirect ADP–>ATP
-ETC
-cheiosmosis
