Question
Which of the following is NOT true of the citric acid cycle?
Succinate dehydrogenase is bound to the outer mitochondrial membrane.
Succinate dehydrogenase channels electrons directly into the electron transfer chain.
ADP is always a positive regulator.
NADH is always a negative regulator.
Oxaloacetate is used as a substrate but is not consumed in the cycle.
A phosphorylated histidine occurs in the mechanism during substrate level phosphorylation.
In the presence of malonate (an analog of succinate) succinate concentrations would increase.

Explanation / Answer
In the presence of malonate (an analog of succinate) succinate concentrations would increase.
This term is not true for citric acid cycle as malonate doesnot have any role in citric acid cycle
