Which cellular process results in the most significant production of ATP? a. oxidative phosphorylation b. Krebs cycle c. glycolysis d. fermentation

Answer is A. Oxidative phosphorylation.

Explanation:

A mechanism or metabolic pathway that produce adenosine triphosphate, ATP, by using the energy produced during the oxidation of nutrients is described as oxidative phosphorylation. This metabolic pathway is known to be the pathway for the production of adenosine triphosphate, ATP in living organisms, i. e, in plants and animals.

It was discovered that, oxidative phosphorylation takes place in the mitochondria, specifically during aerobic respiration.

Note that, aerobic respiration is the type of respiration that occur in the absence of oxygen.
