Question
Why does it make sense for NADH to inhibit all three regulatory steps of the TCA cycle?A.) all of these are correct B.) none of these are correct C.) a high ratio of [NADH/NAD+] would make citric acid cycle reactions less favorable in the forward direction D.) abundant NADH is an indication that the cell has plenty of high energy molecules E.) the concentration of NADH is held relatively constant at steady-state conditions

Explanation / Answer
B.) none of these are correct -answer
------------------------------------
The citric acid cycle is less dynamic when a cell has high ATP/ADP proportion and high NADH/NAD+ proportion. Both proportions show a high vitality charge in the cell demonstrating to a lesser degree a requirement for the vitality releaing responses of the citrus extract cycle.
On the off chance that the measure of NADH in a cell builds with respect to the measure of NAD+ the cell has finished various vitality discharging responses. There is less requirement for the citrus extract cycle to be dynamic; subsequently' the movement of pyruvate dehydrogenase is diminished.
