Answer:
1. COP-II
COP-I is for golgi to ER (retrograde transport)
2. COP-I
3. Glycanase and Glucosidase I
4 : Coat proteins are responsible for formation of clathrin coated vesicle.
So the given statement is true.
5 : Formation of vesicles do not require energy expenditure.
So the given statement is false.
6 : Botulinum toxin causes paralytic effects by inhibiting the release of acetylcholine from presynaptic motor neurons. The signal transduction pathway is blocked.
The answer is Disrupting the G(s) signal transduction pathway.
