E)pinocytosis.

Question

Quizplus · Accepted Answer

Uptake of LDLs occurs via receptor-mediated endocytosis, where LDL particles bind to specific receptors on the cell surface, forming clathrin-coated pits, which are then internalized into the cell via endocytosis. This process requires the specific recognition and binding of the LDL particles to their respective receptors, which is why it is referred to as receptor-mediated endocytosis.
