Final answer:
The cholesteryl esters of HDL can reach the liver via IDL and LDL through receptor-mediated endocytosis.
Step-by-step explanation:
The cholesteryl esters of HDL can reach the liver via IDL and LDL through receptor-mediated endocytosis.
Receptor-mediated endocytosis is a process in which specific substances are taken up by cells through binding to specific receptor proteins on the cell membrane. LDL (low-density lipoprotein) contains cholesteryl esters and binds to LDL receptors on the liver cells. This binding triggers the internalization of the LDL by the liver cells through the formation of clathrin-coated vesicles.
Inside the liver cells, the cholesteryl esters can be metabolized and used for various cellular processes.
