Answer:
During kerbs cycle pyruvate is converted to Acetyl CoA .The so formed Acetyl CoA then enters the krebs cycle.
Explanation:
Pyruvate is the end product of glycolysis.Pyruvate is converted into Acetyl CoA by the catalytic activity of pyruvate dehydrogenase enzyme which uses NAD+ as a coenzyme.
The formation of pyruvate to Acetyl CoA is termed as oxidative decarboxylation.
