The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that "Carboxypeptidase is an exopeptidase." - **Explanation**: Carboxypeptidase is indeed classified as an exopeptidase because it acts on the ends of peptide chains. Exopeptidases are enzymes that cleave peptide bonds from the terminal ends of proteins or peptides. ### Step 2: Understand the Reason The reason states that "It cleaves the N-terminal bond." - **Explanation**: This statement is incorrect. Carboxypeptidase actually cleaves peptide bonds at the C-terminal end of the peptide chain, not the N-terminal. The enzyme responsible for cleaving the N-terminal bonds is called aminopeptidase. ### Step 3: Conclusion Based on the analysis: - The assertion is **true**: Carboxypeptidase is an exopeptidase. - The reason is **false**: It does not cleave the N-terminal bond; it cleaves the C-terminal bond. ### Final Answer The correct answer is that the assertion is true and the reason is false.
