Question

Acetyl-CoA is produced from

• A. pyruvate and a coenzyme
• B. citric acid and a coenzyme
• C. ATP and pyruvate
• D. CO2 and pyruvate

Answer 1

The correct option is A pyruvate and a coenzyme

The process of production of Acetyl CoA is called as transition reaction or link reaction, it links the process of glycolysis ( where glucose is broken down to form two molecules of pyruvate ) to the process of Krebs cycle where pyruvate undergo oxidative decarboxylation and then combines to sulfur-containing coenzyme A to form acetyl CoA.

So, the correct option is ' pyruvate and a coenzyme'.
