Animal cells take up cholesterol via
A) specific receptor proteins on the external surface of the cell membrane.
B) passive transport through the lipid bilayer.
C) clathrin receptors on the external surface of the cell membrane.
D) protein carriers to transport the cholesterol-receptor complex across the membrane.
E) the fusing of clathrin-coated vesicles to the cell membrane.

Question

Quizplus · Accepted Answer

Cholesterol uptake in animal cells is mediated by specific receptor proteins on the external surface of the cell membrane, known as LDL receptors, which bind to low-density lipoprotein (LDL) particles that carry cholesterol. This process is part of receptor-mediated endocytosis.
