Question

In a resting potential, an example of a cation that is more abundant as a solute in the cytosol of a neuron than it is in the interstitial fluid outside the neuron is _____.

Answer 1

A positive potassium cation (K+) could be an example of a solute in the cytosol when it is at its resting potential. To add up, the resting potential difference inside the membranes of a neuron was estimatedly -70 mV wherein aside from potassium ions, sodium ions are also present in the neuron.
