These two opposite processesthe first requiring energy and the second producing energyare referred to as anabolic (building) and catabolic (breaking down) pathways, respectively. Since humans evolved for aerobic activities (Hochachka, Gunga & Kirsch 1998; Hochachka & Monge 2000), it's not surprising that the aerobic system, which is dependent on oxygen, is the most complex of the three metabolic energy systems.The metabolic reactions that take place in the presence of oxygen are responsible for most of the cellular energy produced by the body. School McGill University; Course Title LSCI 230; Uploaded By malipour123. What are the three (3) products created during glycolysis? In stage II of catabolism, the metabolic pathway known as glycolysis converts glucose into two molecules of pyruvate (a three-carbon compound with three carbon atoms) with the corresponding production of adenosine triphosphate (ATP).
