The Na+ concentration is higher outside the cell compared to inside. The K+ concentration is higher inside the cell compared to outside

The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.

What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
None of the following do.
Which term describes the difference in the concentrations of a substance across a cell membrane?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
When does diffusion occur across a cell membrane?
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
During depolarization does the neurons membrane become negative?
Yes. Positive ions (sodium) move across the membrane.

What effect does the leaking of potassium across the membrane have on the membrane potential of Kevin's neurons?
It makes the inside of the neurons more negative.
Describe how dissolved particles move across a plasma membrane form regions of lower to higher concentrations?
Things move across the membrane from lower to higher concentrations by active transport.
