Cholesterol and Cardiovascular Pharmacology Quiz

What is the primary role of cholesterol in cell membranes?

• To transport oxygen in the blood

• To act as a receptor for hormones

• To maintain cell membrane fluidity

• To provide energy for cellular processes

Which type of lipoprotein is known as 'good cholesterol'?

• HDL

• Chylomicrons

• VLDL

• LDL

What is the role of HDL in cholesterol transport?

• To synthesize cholesterol in the liver

• To remove cholesterol from blood vessels

• To convert cholesterol into triglycerides

• To transport cholesterol to tissues

What is the consequence of excessive LDL in the bloodstream?

• Increased energy levels

• Improved immune response

• Atherosclerosis

• Enhanced muscle growth

How do statins primarily lower cholesterol levels?

• By binding to cholesterol in the intestines

• By enhancing cholesterol absorption

• By increasing HDL production

• By inhibiting cholesterol synthesis in the liver

Which enzyme do statins inhibit to reduce cholesterol synthesis?

• PCSK9

• HMG CoA reductase

• Apolipoprotein B100

• Lipoprotein lipase

Which suffix is commonly found in the names of statin drugs?

• olol

• mab

• statin

• pril

What is the primary action of fibrates in cholesterol management?

• Sequestering bile acids

• Blocking LDL receptors

• Increasing HDL levels

• Inhibiting cholesterol absorption

What is the mechanism of action for bile acid sequestrants?

• They enhance triglyceride breakdown

• They inhibit cholesterol synthesis

• They bind to bile acids in the intestine

• They increase LDL receptor expression

PCSK9 inhibitors are used to:

• Decrease LDL receptor degradation

• Increase cholesterol synthesis

• Reduce HDL levels

• Enhance triglyceride storage
