What is the total amount of NADH produced by aerobic respiration?

The total amount of NADH produced by aerobic respiration is indeed 10 NADH. In the process of aerobic respiration, glucose is fully oxidized to carbon dioxide and water through glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation.

During glycolysis, which occurs in the cytoplasm, two molecules of NADH are produced for each molecule of glucose. This is the initial stage of aerobic respiration, where glucose is converted into pyruvate, and energy is captured in the form of NADH.

Following glycolysis, if oxygen is present, pyruvate enters the mitochondria where it is converted into acetyl-CoA. During this step, an additional molecule of NADH is generated for each of the two pyruvate molecules generated from one glucose molecule, resulting in a total of two more NADH.

Next, during the citric acid cycle, each acetyl-CoA that enters the cycle results in three molecules of NADH being produced. Since each glucose yields two acetyl-CoA molecules, the citric acid cycle will produce a total of six NADH (3 NADH x 2 acetyl-CoA).

Adding all of these together, we have:

• 2 NADH from glycolysis
