How many ATP molecules are produced from one glucose molecule?

Answer 1

Through the complex processes of glycolysis, Kreb's Cycle and the electron transfer system, a net gain of 38 ATP are produced from the breakdown of one glucose molecule.

Answer 2

In aerobic respiration, one glucose molecule typically produces 36-38 ATP molecules through glycolysis, the Krebs cycle, and the electron transport chain. In anaerobic respiration, such as fermentation, the number of ATP molecules produced is lower, around 2 ATP molecules.

Answer 3

In aerobic respiration, one molecule of glucose yields 38 ATP molecules, eight produced during glycolysis, six from the link reaction and 24 from the Krebs cycle.

The net gain is 36 ATP, as two of the ATP molecules produced from glycolysis are used up in the re-oxidation of the hydrogen carrier molecule NAD.

Therefore;

There are 38 ATP molecules produced

but net gain is 36 ATP
