Question

What pathway provides the longest-lasting supply of ATP?

Answer 1

Oxidative phosphorylation provides the highest amount of ATP in the process of respiration, however how long the ATP lasts is dependant on where the process is taking place in the body.

Answer 2

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)
