Why is chemiosmosis more efficient than glycolysis and krebs cycle?Watch
The net amount of ATP made by glycolysis per 1 molecule of glucose is 2, and for the Krebs' cycle, 2 ATP is made for each molecule of glucose.
10 NADH molecules are re-oxidised by chemiosmosis and 2 FADH, which yield 30 ATP molecules and 4 ATP molecules respectively.
Essentially 34 ATP comes from chemiosmosis. while only 4 from glycolysis and the Krebs' cycle combined.
