The resting membrane potential of a cell relies on the fact that the extracellular environment is relatively positive and the intracellular environment is relatively negative.

Question

The resting membrane potential of a cell relies on the fact that the extracellular environment is relatively positive and the intracellular environment is relatively negative.

Answer 1

I'm assuming this is a true/false question. The statement is true:

The resting membrane potential of a cell is maintained by the concentration gradient of ions across the cell membrane. The intracellular environment is relatively negative compared to the extracellular environment, which is relatively positive. This difference in charge creates an electrical gradient that is maintained by the selective permeability of the cell membrane, which allows certain ions to move in and out of the cell to maintain the resting membrane potential.

The resting membrane potential is maintained by the action of ion pumps, such as the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell. This helps to maintain the electrical gradient and the resting membrane potential. Additionally, selective ion channels in the cell membrane allow ions to diffuse from one side of the membrane to the other, contributing to the resting membrane potential.

I hope this explanation helps!!!
