Answer:
(B) preparatory reaction - cristae of mitochondria
Explanation:
The oxidative decarboxylation of pyruvate into acetyl-CoA is also called preparatory reaction. Â
Glycolysis occurs in cytoplasm and forms two molecules of pyruvate from one molecule of glucose. The transport proteins transport pyruvate from cytoplasm to the matrix of mitochondria. Â
Pyruvate dehydrogenase enzyme complex is present in mitochondria which carry out oxidative decarboxylation of pyruvate and forms one molecule of acetyl CoA from each pyruvate molecule.
