Receptor mediated endocytosis involves vesicles coated with ____.
a. COPI proteins
b. COPII proteins
c. clathrin proteins
Homework Answers
Receptor mediated endocytosis involves vesicles coated with clathrin proteins and hence is also known as clathrin dependent endocytosis.
The process involves the plasma membrane-spanning receptors getting bound by a ligand. A signal is then sent through the membrane. This leads to the coating of the membrane and formation of a membrane invagination. Then opsonisation of the receptor and its ligand takes place in clathrin-coated vesicles.
