When a neuron responds to a particular neurotransmitter by opening gated ion channels, the neurotransmitter is serving as what part of the signal pathway? (2 points)
a.transducer signal molecule
b.relay molecule receptor

When the neurons responds to the neurotransmitter by opening the gated ion channels then the neurotransmitter is serving the transducer signal molecule.

Binding of the neurotransmitter leads to an immediate conformational change which opens the gate of channel and allows the movement of ions to cross the voltage gated channels.

This changes the membrane potential within 0.1 -2 milliseconds.This helps in signal transduction.
