Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?

Options

(a) Fructose 1,6 – bisphosphate
(b) Pyruvic acid
(c) Acetyl CoA
(d) Glucose – 6 – phosphate

Correct Answer:

Acetyl CoA

Explanation:

Acetyl CoA is common to respiration mediated breakdown of fats, carbohydrates and proteins. Facts are broken down to fatty acid and glycerol and again fatty acid degraded to acetyl Co-A. Protein first degraded by proteases to individual amino acids which deaminated to pyruvic acid and further decarboxylated to acetyl Co-A.
