One glucose on complete oxidation yield 36 ATP. During this oxidation of glucose, what is the contribution of Krebs cycle via oxidative phosphorylation?

In one Krebs cycle, 3 NADH and 1 FADH2 are produced. 1 NADH= 3ATP and 1 FADH2 = 2 ATPTotal number of ATP produced through 1 Krebs cycle- 11The Krebs cycle is repeated twice for one molecule of glucose.Therefore, total number of ATP is= 11 x 2= 22ATP
