Answer #1

Answer;

The right choice is: (b)

Explanation: Metabotropic neurotransmitter receptors move more slowly than ionotropic neurotransmitter receptors because activation of metabotropic receptors depends on various types of molecules in the cell involving second messenger pathway and since there are more steps involved the signalling through metabotropic receptors is slow when compared to ionotropic receptors which are ligand activated and they show quick and fast action.
