Membrane proteins can serve a variety of key functions:
Junctions – Serve to connect and join two cells together.
Enzymes – Fixing to membranes localises metabolic pathways.
Transport – Responsible for facilitated diffusion and active transport.
Recognition – May function as markers for cellular identification.
I believe there are three correct answers from the choices listed above. The statements that describe an element are as follows:
<span>An element is a pure substance that cannot be broken down into a simpler form.

However, Catherin-coated vesicles bud from the Golgi on the outward secretory pathway and from the plasma membrane on the inward endocytic pathway. GTP is hydrolized. the ring constricts. This starts the shaping of the membrane into a vesicle. In conclusion to this statement small GTP-binding protein dynamin .forms a ring around the neck.
