Question
Number of ATP produced from one pyurvic acid during conversation to acetyl Co-A
Open in App
Solution
The correct option is C 3
During respiration, the pyruvic acid is converted into acetyl-CoA by the enzyme pyruvate dehydrogenase. This enzyme carries oxidative decarboxylation of one molecule of pyruvic acid to produce one molecule of acetyl- CoA releasing one molecule of carbon dioxide. This reaction also helps in producing one molecule of reduced NADH in the process. One molecule of reduced NADH is equivalent to 3 molecules of ATP, which are produced by oxidation of reduced NADH in the respiratory electron transport chain. Thus, the correct answer is option B.
