Question

Assertion: Krebs cycle also plays a significant role in anabolism.
Reason: The intermediates formed in the TCA cycle serve as a substrate for the synthesis of amino acids.

• A. Both assertion and reason are true and reason is the correct explanation of assertion.
• B. Both assertion and reason are true and reason is not the correct explanation of assertion.
• C. Assertion is true but the reason is false.
• D. Both assertion and reason are false.

Answer 1

The correct option is A Both assertion and reason are true and reason is the correct explanation of assertion.

Krebs cycle plays an important role in formation of certain intermediates which are involved in the synthesis of amino acids. For example, oxaloacetate which forms aspartate and asparagine; and alpha-ketoglutarate which forms glutamine, proline, and arginine.
