Krebsor tricarboxylic acid (TCA) cycle for conversion of pyruvate to CO 2. Aerobic Respiration: 36-38 ATPs Anaerobic Respiration: 2-36 ATPs Fermentation: 2 ATPs. Like many other animals, humans produce ATP through three metabolic energy pathways that consist of many enzyme-catalyzed chemical reactions: the phosphagen system, glycolysis and the aerobic system. The three branched-chain amino acids, isoleucine, leucine, and valine enter the catabolic pathway via the action of the same two enzymes. Co 2 and H 2 O ) during the first, large molecules, such running! These simpler molecules can be used as building blocks for other molecules that cells (and thus, organisms) need to operate, such as other proteins, glycogen and triglycerides.
