Q: Can membrane potential be affected by external factors?
Some common misconceptions about membrane potential include:
The regulation of membrane potential is a complex process, involving the coordinated effort of various ion channels, pumps, and exchangers. Ion channels, such as voltage-gated sodium and potassium channels, control the flow of ions across the membrane. Pumps, like the sodium-potassium pump, maintain the balance of ions by actively transporting them against their concentration gradient. Exchangers, such as the sodium-calcium exchanger, help regulate the levels of ions by exchanging one ion for another.
Common Misconceptions

Membrane potential is the difference in electrical charge between the inside and outside of a cell. This phenomenon is a result of the movement of ions, such as sodium, potassium, and chloride, across the cell membrane. The membrane is semi-permeable, allowing certain ions to pass through while restricting others. This selective permeability creates a potential difference, which is measured in millivolts (mV). The membrane potential plays a crucial role in various cellular processes, including nerve conduction, muscle contraction, and hormone secretion.
