Question

When a neuron is a rest, the sodium ions flow through the membrane at a very low rate. Why is this?
The sodium ions are negatively charged, and are not drawn into the negatively charged neuron
Sodium ions are much larger than calcium, potassium, or chlorine ions
Sodium ions always flow through the membrane at a very low rate, whether the neuron is at rest or
not at rest
The sodium ion channels are closed when a neuron is at rest

Expert Solution

Step 1: Introduction:

Ion channels are essential components of neurons that allow for the production and transmission of electrical impulses known as action potentials.
These channels allow certain ions to pass across the neuronal membrane in a selective manner, resulting in rapid changes in membrane potential.
This dynamic mechanism enables information transmission in the nervous system, promoting communication between neurons and enabling sophisticated brain activities such as learning, memory, and sensory perception.
