The citric acid cycle is a closed loop; the last part of the pathway reforms the molecule used in the first step. the citric acid cycle? In this process, pyruvate molecules are completely oxidized to carbon dioxide, while many coenzyme molecules are reduced (gain and carry electrons). The citric acid cycle occurs in the inner membrane of mitochondrion. The Citric Acid Cycle. Recall that in glycolysis, glucose is converted to two molecules of pyruvate, and then pyruvate is further oxidized to acetyl CoA. Citric Acid Cycle. New questions in Biology.

The outline below is typical of the metabolism of carbohydrates, which proceeds through glycolysis to form pyruvate and then through acetyl CoA to enter the TCA cycle. During the eight reactions that take place, for every molecule of acetyl-CoA the cycle produces three NADH and one flavin adenine dinucleotide (FAD/FADH2), along with one molecule of ATP.
