When low density lipoproteins (LDL) are brought into the cell in the process of receptor mediated endocytosis

Question

Quizplus · Accepted Answer

In receptor mediated endocytosis, the LDL particles bind to LDL receptors on the cell membrane, forming a complex which is then internalized in clathrin-coated vesicles. After the internalization, the LDL receptors are separated from the LDL particles and recycled back to the cell membrane. The LDL particles are transported to lysosomes where they are degraded, releasing the cholesterol they carry into the cytoplasm. Therefore, choice B is the best answer as it correctly states that LDL receptors are recycled to the cell membrane.
