Answer: Option A
Explanation:
The opening and closing of the voltage gated channels depends on the type of the receptors on it. The cells responds according to the receptors found on the cell membrane.
According to the voltage gated channels the domains that are sensitive towards the gated channels are he particular neurotransmitter can have different receptors on them.
An excitatory postsynaptic potential causes channels to move in and shows excitatory response.
Whereas in case of the Inhibitory postsynaptic potential the channels are closed and they show inhibitory response.
Hence, some of the channels remains closed and some of them remains open after signals.
