Conversion of an electrical signal to a chemical signal at the nerve terminus does not require which of the following? (a) depolarization of the membrane (b) activation of the Ca+ channel (c) activation of the Nat channel (d) formation of synaptic vesicles 17. The Acetylcholine receptor is an example of which of the following types of ion channels? (a) voltage-gated (b) ligand-gated (c) Stress-gated (d) none of the above 18. Propagation of an action potential along an axon is bi-directional (a) true 19. Where does most membrane synthesis take place in eukaryotic cells? (c) false (a) lysosome (b) ribosome (c) smooth ER (d) Golgi apparatusExplanation / Answer
Ans 10 : a) dynamin
The piching off of vesicles from the parent membrane requires a GTP binding protein , which is called as dynamin.
This vesicle is called as endosome , to which the protein molecules are coated called as clathrin .
