Multiple choice

Assertion (A) : Citric acid has less 'Respiratory Quotient' in comparison to lipids. Reason (R) : Citric acid has relatively more oxygen in comparison to lipids

  1. Both A and R are individually true and R is the correct explanation of A.

  2. Both A and R are individually true but R is not the correct explanation of A.

  3. A is true but R is false.

  4. A is false but R is true.

Explanation

The Respiratory Quotient (RQ = CO2 produced/O2 consumed) depends on substrate composition. Citric acid (C6H8O7) has RQ = 6/7 ≈ 0.86, while lipids typically have RQ around 0.7. Citric acid actually has HIGHER RQ than lipids because it contains more oxygen relative to carbon. Therefore Assertion A is false (citric acid has MORE RQ, not less). Reason R is true (citric acid does have relatively more oxygen than lipids).
