Q. In Krebs cycle, OAA accepts acetyl CoA to form :
(a) Citric acid
(b) Oxalosuccinic acid
(c) Fumaric acid
(d) Succinyl CoA
Solution :
Correct option : A Citric acid cycle is also called as Krebs cycle or tricarboxylic acid cycle. It is a metabolic cycle through which aerobic organisms obtain their energy. Pyruvate produced in glycolysis first gets converted into acetyl CoA before entering citric acid cycle. This acetyl CoA is accepted by oxaloacetic acid (OAA) to form citric acid, the first product of the cycle. Thus, the correct answer is ‘Citric acid.’
