Question: NSAIDs relieve pain and inflammation mainly by inhibiting which enzyme?
Explanation: NSAIDs inhibit COX, reducing prostaglandin production.
Other fields (not shown on cards):
Choices: DNA polymerase
cyclooxygenase (COX)
amylase
ATP synthase
Correct: B

Question: Beta-blockers act by blocking which receptors?
Explanation: They block beta-adrenergic receptors, lowering heart rate and BP.
Other fields (not shown on cards):
Choices: beta-adrenergic
histamine
opioid
dopamine
Correct: A

Question: Statins lower cholesterol by inhibiting which enzyme?
Explanation: Statins inhibit HMG-CoA reductase, the rate-limiting step in cholesterol synthesis.
Other fields (not shown on cards):
Choices: HMG-CoA reductase
cyclooxygenase
lipase
kinase
Correct: A

Question: ACE inhibitors lower blood pressure by blocking the conversion of:
Explanation: Blocking this conversion reduces vasoconstriction.
Other fields (not shown on cards):
Choices: glucose to glycogen
angiotensin I to angiotensin II
T4 to T3
dopamine to norepinephrine
Correct: B

Question: Insulin lowers blood glucose mainly by promoting glucose:
Explanation: Insulin drives glucose uptake from the blood into cells.
Other fields (not shown on cards):
Choices: uptake into cells
excretion in urine
production in the liver
breakdown in the stomach
Correct: A

Question: Warfarin's anticoagulant effect involves interfering with which vitamin?
Explanation: Warfarin inhibits vitamin K–dependent clotting factors.
Other fields (not shown on cards):
Choices: Vitamin C
Vitamin K
Vitamin D
Vitamin B12
Correct: B

Question: Opioids relieve pain by acting on which receptors?
Explanation: Opioids bind opioid receptors in the nervous system.
Other fields (not shown on cards):
Choices: opioid (e.g., mu) receptors
beta receptors
histamine receptors
insulin receptors
Correct: A
