Verified
LDLs are taken into a cell by the process of ________.
A) simple diffusion
B) osmosis
C) receptor mediated endocytosis
D) HDL carrier molecules
E) facilitated diffusion
Receptor Mediated Endocytosis
This is a cellular process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being absorbed.
LDLs
Low-density lipoproteins, often referred to as "bad" cholesterol, involved in the transport of cholesterol to cells.
Simple Diffusion
The movement of molecules from an area of higher concentration to an area of lower concentration without the need for energy.

Final Answer :
C
Explanation :
LDLs (Low-Density Lipoproteins) are taken into cells through receptor-mediated endocytosis, a process where cells internalize molecules (such as LDLs) by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being internalized.
