Answer: Option D
Step-by-step explanation:
Apolipoprotein B is a type of apolipoprotein that bind lipids including cholesterol and forming the main organizing protein in lipoproteins such as in the low density lipoprotein. The low density lipoprotein serves as a vehicle to transport cholesterol into the cell through the receptor mediated endocytosis process. This process allows for the movement of larger molecules from the outside of the cell into the cell. Thus apolipoprotein can bind as ligands to the LDL receptors and allow for the transport of fats into the cell..
