- Glycolysis
- Krebs cycle
- Terminal oxidation
During glycolysis glucose changes to pyruvic acid gaining total energy as 2 ATP molecules and 2 molecules of NADH
2 then later on in Krebs cycle 30 ATP molecules and 2 FADH
2 are produced. One NADH
2 produces 3 ATP molecules while one FADH
2 produces two ATP molecules. Therefore in complete oxidation of one molecule of glucose, a total of 38 ATP's are gained.
So, the correct option is ' 38'.
