Answer: oxidative phosphorylation pathway
Explanation: The more the work engaged in, the faster the energy consumption by the body and one pathway sufficiently powerful to keep up with this demand by the body mostly during aerobic respiration is the oxidative phosphorylation metabolic pathway, a pathway involving the use of enzymes by cells to break down nutrients releasing energy that is captured in producing ATP. By a series of electron carrier molecules, electrons are transferred from NADH or FADH 2 to oxygen producing 2 or 3 molecules of ATP as the case may be. Aerobic respiration being much more efficient can produce up to 38 ATP in total from a molecule of sugar (glucose)
