Propagation of an action potential along an axon is bi-directional efalse (a) true 19. Where does most membrane synthesis take place in eukaryotic cells? (a) lysosome (b) ribosome (c)smooth ER )Golgi apparatusExplanation / Answer
Answers
1yes dynamin is required for pinching off the vesicles.
2 c is the correct answer
3here sodium pump means only single ion transport and it is uniport in nature.
4voltage gated is the correct answer
5 sodium channels are required through which resting potential is converted into action potential.
6 answer is deploraization is the correct.
7 ligand gated ion channels is correct answer
8 false because of refractory period it prophages unidirectionally
9 smooth ER is the correct answer because membrane is made up of lipid and lipid synthesis takes place in ER.
