Question

Which metabolite is common in respiration mediated breakdown of fats, carbohydrates and proteins ?

• A. Acetyl CoA
• B. Glucose 6-phosphate
• C. Fructose 1, 6-biphosphate
• D. Pyruvic acid

Answer 1

The correct option is A Acetyl CoA

Acetyl Co-A is common in respiration mediated breakdown of fats, carbohydrates, and proteins. It is an integral part of many cellular processes. It provides carbon atom required for the citric acid cycle. It is produced via glycolysis (breakdown of carbohydrates), gluconeogenesis (breakdown of protein) and fatty acid oxidation.

Thus, the correct answer is option A.
