Detailed explanation-1: -Expert-Verified Answer. Glycolysis and Krebs Cycle grants you 4 ATP (2 each) and ETC grants you 32 ATP..

Detailed explanation-2: -Oxidative phosphorylation In 1951 it was discovered that the transfer of one pair of electrons to oxygen results in the formation of three molecules of ATP. Oxidative phosphorylation is the major mechanism by which the large amounts of energy in foodstuffs are conserved and made available to the cell.

Detailed explanation-3: -All of them catabolize glucose to form ATP. The reactions of cellular respiration can be grouped into three main stages and an intermediate stage: glycolysis, Transformation of pyruvate, the Krebs cycle (also called the citric acid cycle), and Oxidative Phosphorylation.

Detailed explanation-4: -In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes-glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation-to produce ATP.
