Questions
How many ATP molecules are produced during oxidative phosphorylation, if two molecules of pyruvate is used as respiratory substrate?
detailed solution
Correct option is D
If one molecule of pyruvate is used as a respiratory substrate then first it enters into link reaction and forms 1 molecule of NADH+H+. Then the acetyl CoA formed enters Kreb's cycle and forms 3 NADH+H+, 1 FADH2Total 4 NADH+H+ are produced and when they are oxidised results in the formation of = 4 x 3= 12 ATP in ETSTotal 1 FADH2is produced and when it is oxidised through ETS, it results in the formation of 2 ATPTotal number ATP molecules are produced during oxidative phosphorylation, if one molecule of pyruvate is used as respiratory substrate is 12+2= 14ATPTotal number ATP molecules are produced during oxidative phosphorylation, if two molecules of pyruvate is used as respiratory substrate is 14x2= 28 ATPTalk to our academic expert!
