During TCA cycle, oxidative phosphorylation occurs 4 times and in oxidative phosphorylation most enzymes are in inner mitochondrial membrane, so why not the answer is A?

Peninah said: (May 3, 2016)  
Option C is correct. Because most of the citric acid cycle are found in the matrix.

I believe enzymes are located in the inner mitochondrial membrane. Even the enter transfer of electrons in the respiratory chain has enzyme-complexes at the inner mitochondrial membrane.
