The correct Answer is:
### Step-by-Step Text Solution: 1. **Understanding the Assertion (A)**: The assertion states that "Pumps are proteins that use energy to transport substances." This is true because pumps are indeed proteins that facilitate the movement of ions or molecules across cellular membranes, and they do so by utilizing energy, typically in the form of ATP. 2. **Understanding the Reason (R)**: The reason states that "Pumps are highly specific like enzymes." This statement is partially true. While pumps do exhibit specificity in the substances they transport, they are not as specific as enzymes. Enzymes typically catalyze reactions for only one specific substrate, whereas a single type of pump can transport multiple types of molecules. 3. **Analyzing the Relationship**: Since the assertion is true and the reason is false, we can conclude that the two statements do not support each other. The assertion stands correct on its own, but the reason does not accurately describe the nature of pumps in comparison to enzymes. 4. **Conclusion**: Therefore, the correct answer to the assertion and reason question is that the assertion is true, but the reason is false. ### Final Answer: - Assertion (A) is true. - Reason (R) is false.
