Why does an increase in NADH/NAD+ ratio cause an increase in the rate of citric acid cycle?
Homework Answers
The increase in the NADH/NAD+ ratio actually prevents the citric acid cycle as it inhibits the target enzymes. The increase in the ratios prevents the krebs cycle by the mass action on all of the 3 stages that has reduction of NAD, increased NADH transfers the equilibrium to the NAD.
hope the answer helps.

Based on our discussion in class, high levels of NADH would likely A. cause pellagra B. stimulate glycolysis C. slow down the movement of molecules through the citric acid cycle D. slow down oxidative phosphorylation E. break down carbohydrates 27. What purpose does fermentation serve? A. It regenerates NAD* from NADH to keep glycolysis going in the absence of oxygen. B. It allows for the production of NADH, which keeps the electron transport chain going. C. It produces an...

QUESTION 25 The citric acid cycle cannot function if o2 is not available; why is this OA. O2 is required for the redox reactions of the citric acid cycle. B. All of these answers are correct OC. The electron transport chain will not function without 02, thus the NAD+ and FAD needed for the citric acid cycle will not be regenerated. OD. None of these answers are correct O E 02 is the final electron acceptor of the citric acid...
