In what way does the interior surface of a cell membrane of a resting (nonconducting) neuron differ from the external environment? the interior is
select one:
a. positively charged and contains more sodium
b. positively charged and contains less sodium
c. negatively charged and contains less sodium
d. negatively charged and contains more sodium

The interior of a resting neuron differs from the external environment because the interior is negatively charged and contains less sodium (Option c).

The resting potential of a neuron is determined by the concentration of different types of ions (positive and negative) on the outside and inside of the cell.

At the resting potential, the interior of a neuron is polarized to a negative charge.

When an action potential reaches the neuron, it depolarizes the membrane and opens sodium channels in the cell membrane, thereby sodium ions enter the cell, the cell becomes more positive and becomes depolarized.

In conclusion, the interior of a resting neuron differs from the external environment because the interior is negatively charged and contains less sodium.

option C) negatively charged and contains less sodium

Explanation:

In the absence of any stimulus, a neuron is said to be resting. During this time, more positively charged potassium ions (K+) than sodium ions (Na+) occupy the interior of its cell membrane, whereas more sodium ions than potassium occupies the exterior - making the cell membrane to be electrically Polarized with net positive charge outside and a net negative charge inside the cell membrane.

Thus, the interior is negatively charged and contains less sodium ions
