Question
Assertion: Fatty acid would be broken down to acetyl CoA before entering the respiratory pathway when it is used as substrate.Reason: When the organism need to synthesize fatty acid, acetyl CoA would be withdrawn from the respiratory pathway for it.Both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.Both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.Assertion is True but the Reason is False.Both Assertion & Reason are False.
Solution
Both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
Here's why:
The assertion is true because fatty acids are indeed broken down into acetyl CoA before entering the respiratory pathway. This process is known as beta-oxidation. During beta-oxidation, the fatty acid molecules are broken down in the mitochondria to generate acetyl CoA, which is then used in the Krebs cycle of cellular respiration to generate energy.
The reason is also true and explains the assertion correctly. When the organism needs to synthesize fatty acids, acetyl CoA is withdrawn from the respiratory pathway. This is because acetyl CoA serves as a building block for the synthesis of fatty acids. Therefore, when the body needs to produce more fatty acids, it diverts acetyl CoA from the respiratory pathway to fatty acid synthesis.
