Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): When the carbohydrates and fats are metabolised, the energy is liberated.
Reason (R): As the fat metabolism, produced more energy than carbohydrates.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Always ensure to distinguish between supportive details and explanations when evaluating such questions.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:

• This is an Assertion-Reason question on energy metabolism.

Step 2: Detailed Explanation:

• Assertion (A): Metabolism of carbohydrates and fats releases energy. This is correct.

• Reason (R): Fat gives more energy per gram (about 9 kcal) than carbohydrate (about 4 kcal). This is also correct.

• However, the higher energy yield of fat does not explain why energy is liberated when carbohydrates and fats are metabolised; the release of energy occurs for both in any case. So (R) is not the correct explanation of (A).

Step 3: Final Answer:
The correct option is (B) Both (A) and (R) are correct but (R) is not the correct explanation of (A).
