Receptor mediated endocytosis requires:: (A) Clatharin, (B) Dynamin, (C) Actin, (D) All of the above
Answer is D. Clathrin-mediated endocytosis occurs at membrane indentations where the protein clathrin accumulates. Clathrin molecules have the shape of triskelions, with three "legs" radiating from a central hub. At the neck of the vesicle, the GTP-binding protein dynamin is involved, either directly or indirectly, in pinching off the vesicle. Contractile filaments of actin and myosin are also involved.
