Detailed explanation-1: -One molecule of NADH produces 3 molecules of ATP and one molecule of FADH2 produce 2 molecules of ATP. In ETS 10 NADH molecules are produced while 2 FADH2 molecules are formed. Therefore, the total ATP generated from these NADH and FADH2 molecules is 34 molecules.

Detailed explanation-2: -The electron transport chain is the final step of cellular respiration where 34 ATP molecules are produced.

Detailed explanation-3: -Electron Transport System generates 32 or 34 ATP molecules and is the cell’s main source of energy. Thus, the electron transport system produces the most ATP in cellular respiration.

Detailed explanation-4: -There are multiple stages of cellular respiration, each with their own ATP output. One of the stages, glycolysis makes a net 2 ATP molecules. Another stage, the Krebs cycle makes a net 2 ATP molecules. The most productive stage, the electron transport chain makes 32 or 34 ATP molecules.

Detailed explanation-5: -The electron transport system produces 34 molecules of ATP out of a total of 38 molecules. During glycolysis, two ATP molecules are created inside the mitochondria and two ATP molecules are produced outside the mitochondria.
