Prazosin can be used for the treatment of hypertension. It acts as

Correct Answer: C

Rationale: Certainly! Prazosin is an alpha-1 antagonist, which means it blocks the activation of alpha-1 adrenergic receptors. By blocking these receptors, prazosin leads to vasodilation and reduced peripheral vascular resistance, ultimately lowering blood pressure. The other options are not correct because prazosin does not act as a beta-1 antagonist (B), beta-2 agonist (D), or alpha-1 agonist (A) in the context of treating hypertension.

Correct Answer: A

Rationale: Step 1: Nicotinic AChRs are ion channels that allow the passage of ions across the cell membrane in response to acetylcholine. Step 2: The ion channels are not protein-bound or slow, so option B is incorrect. Step 3: Nicotinic AChRs are not G-coupled receptors, so option C is incorrect. Step 4: Nicotinic AChRs are located on the cell membrane, making them water-soluble, so option A is correct. Step 5: Nicotinic AChRs are not intracellular receptors, so option D is incorrect.
