specialized proteins that regulate potassium ion flow in cells
Potassium channels are specialized proteins found in the cell membrane that allow potassium ions (K+) to pass in and out of the cell. They play a crucial role in maintaining the cell's electrical balance and are essential for various physiological processes, including nerve signal transmission, muscle contraction, and heart function. These channels are highly selective, ensuring that only potassium ions can pass through, which helps regulate the cell's internal environment.
