AIIMS 2018 Chemistry Proteins Assertion Reason Question
Proteins are made up of α-aminoacids. During this formation, NH₂ group of one amino acid condenses with COOH of the other with elimination of a water molecule to form a peptide bond.
Both assertion and reason are correct and reason is the correct explanation of the assertion.
Both assertion and reason are correct but reason is not the correct explanation of the assertion.
Assertion is correct but reason is incorrect.
Assertion is incorrect but reason is correct.
Correct Answer
Detailed Explanation
Option C is correct because the assertion accurately states that proteins are formed from α-amino acids through the condensation of the NH₂ group of one amino acid with the COOH group of another, resulting in a peptide bond. However, the reason provided is incorrect as it does not specify that the elimination of a water molecule (H₂O) occurs during this process; instead, it merely describes the formation of the bond without detailing the reaction mechanism.
Option A is incorrect because, while the assertion is true, the reason does not correctly explain it. Option B is incorrect for the same reason; although both statements are true, the reason fails to adequately explain the assertion. Option D is incorrect because the assertion is indeed correct, making it impossible for the reason to be the only correct statement.
