The correct Answer is:
To solve the question, we need to evaluate the assertion and the reason given. ### Step 1: Analyze the Assertion The assertion states: "Enzymes have active sites that hold substrate molecules for a chemical reaction." - This statement is **true**. Enzymes are biological catalysts that facilitate chemical reactions by binding to substrate molecules at their active sites. ### Step 2: Analyze the Reason The reason states: "Drugs compete with natural substrate by attaching covalently to the active site of the enzyme." - This statement is **false**. While it is true that drugs can compete with natural substrates, they typically do so through non-covalent interactions (like hydrogen bonds, ionic interactions, and Van der Waals forces) rather than covalent bonds. ### Step 3: Determine the Relationship Between Assertion and Reason - The assertion is correct, but the reason is incorrect. Therefore, the reason does not explain the assertion. ### Conclusion Based on the analysis: - The correct answer is (d) Assertion is correct statement, reason is wrong statement. ---
