Question

Quizplus · Accepted Answer

Cholesterol is primarily taken up by cells through receptor-mediated endocytosis, which involves the binding of cholesterol to specific receptors on the cell membrane, followed by internalization of the receptor-cholesterol complex into the cell through the process of endocytosis. This is a highly regulated and selective process that enables cells to control their cholesterol levels and maintain proper cellular function. Other mechanisms such as pinocytosis, phagocytosis, and active transport may also occur, but they are less commonly involved in cholesterol uptake.
