D) proteins and small ions
E) membranes and membrane proteins
Resting Potential
Membrane potential of a neuron at rest.
Millivolts
A unit of electric potential or electromotive force equal to one thousandth of a volt, commonly used in measuring electrical potentials in cells and batteries.
Neuron

Final Answer :
D
Explanation :
The resting potential of a neuron occurs due to the distribution of charged proteins and small ions inside and outside of the cell. Specifically, there is a higher concentration of positively charged ions (such as potassium) inside the cell, and a higher concentration of negatively charged ions (such as chloride) outside the cell. Additionally, there are negatively charged proteins inside the cell that also contribute to the overall negative resting potential.
