Match List-I with List-II. List-I (Respiratory Substrate) List-II (RQ Value) (A) Carbohydrates (I) 0.9 (B) Proteins (II) 0.7 (C) Tripalmitin (III) 1.0 Choose the correct answer from the options given below:
Options
- A(A)-(I), (B)-(III), (C)-(II)
- B(A)-(III), (B)-(II), (C)-(I)
- C(A)-(II), (B)-(III), (C)-(I)
- D(A)-(III), (B)-(I), (C)-(II)
Correct answer
D. (A)-(III), (B)-(I), (C)-(II)
Step-by-step solution
The respiratory quotient (RQ) is the ratio of the volume of CO₂ evolved to the volume of O₂ consumed during respiration. For carbohydrates, the RQ value is 1.0 because equal volumes of CO₂ and O₂ are evolved and consumed, respectively. When proteins are used as respiratory substrates, the RQ value is approximately 0.9 . For fats like tripalmitin, the RQ value is less than 1 , specifically 0.7 . Therefore, the correct matching is (A)-(III), (B)-(I), (C)-(II). Answer: (A)-(III), (B)-(I), (C)-(II)
