Question

What is the term for protein channels that connect two neurons at an electrical synapse?

a. synaptic vesicles

b. voltage-gated ion channels

c. gap junction protein

d. sodium-potassium exchange pumps

Short answer

Option c is the correct answer.

Step-by-step solution

Introduction

Even though there are fewer electrical synapses than chemical synapses, these connections still play crucial and distinctive roles in all neurological systems. Compared to chemical synapses, electrical synapses have a very different method of neurotransmission.

The explanation for the correct answer

The presynaptic and postsynaptic membranes are really physically joined by channel proteins, generating gap junctions, in an electrical synapse. Current can flow directly from one cell to the next thanks to gap junctions. The huge gap junction pores allow for the diffusion of ATP and other molecules in addition to the ions that transport this current.

The explanation for incorrect options

Therefore, other options have become irrelevant.
