Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Impulse transmission across electrical synapses is always faster than that of a chemical synapse.

Reason (R) : Electrical current flows directly from one neuron into the other as the pre synaptic membrane and post synaptic membranes are in close proximity.

In light of the above statements, choose the correct answer from the option given below.

Both (A) and (R) are true and (R) is the correct explanation of (A).

Electrical synapses do indeed allow for faster impulse transmission compared to chemical synapses. This is because the electrical signal passes directly from one neuron to another through gap junctions, without the need for neurotransmitter release and synaptic delay.
The reason provided explains why electrical synapses allow for faster transmission. The close proximity of the pre-synaptic and post-synaptic membranes facilitates the rapid flow of electrical current between neurons.
