Unlike glycolysis, the citric acid cycle is a closed loop: The last part of the pathway regenerates the compound used in the first step. B) cytosol C) cytoplasm. 0 0. C. In the mitochondria inside of the matrix of MX. 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. intermembrane space of mitochondria. Lipogenesis is the metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. Where in the cell the citric acid (Krebs) cycle takes place? the citric acid cycle?
