Question

Voltage-regulated channels are located

A) within the cytosol only.
B) in the membranes of dendrites only.
C) in the membranes of axons only.
D) on the neuron cell body only.
E) in the membranes of dendrites, in the membranes of axons, and on the neuron cell body.

Answer 1

Voltage-regulated channels are located in the membranes of dendrites, axons, and on the neuron cell body, contributing to the generation and propagation of action potentials for neural communication.

Step-by-step explanation:

Voltage-regulated channels, also known as voltage-gated ion channels, are integral membrane proteins that allow ions to pass through the neuron's membrane in response to changes in membrane potential.

These channels are not restricted to one particular area of the neuron. Instead, they are located in the membranes of dendrites, in the membranes of axons, and on the neuron cell body.

This distribution allows for the generation and propagation of action potentials along the neuron, facilitating neural communication.
