AP BIOLOGY

Detailed explanation-1: -Glycolysis produces 2 ATP molecules, and the Krebs cycle produces 2 more. Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules.

Detailed explanation-2: -In the Krebs cycle, two ATP, six NADH +H+, and two FADH2 were produced. A net of four ATPs was produced from glycolysis through the Krebs cycle. More ATP will be produced from reduced coenzymes in the mitochondria during the electron transport chain and oxidative phosphorylation.

Detailed explanation-3: -Fermentation. Some organisms are able to continually convert energy without the presence of oxygen. They undergo glycolysis, followed by the anaerobic process of fermentation to make ATP.

Detailed explanation-4: -Answer and Explanation: Among oxidative phosphorylation, fermentation, and glycolysis, oxidative phosphorylation produces the most amount of adenosine triphosphate (ATP).
