potassium channels

Potassium channels are specialized proteins embedded in cell membranes that control the flow of potassium ions (charged particles) in and out of cells. They help regulate important functions like nerve signaling, muscle contractions, and maintaining balanced electrical activity within cells. These channels open or close in response to changes in the cell’s environment, ensuring proper communication and function. By managing potassium movement, they contribute to setting the cell’s electrical resting state and facilitate rapid responses to stimuli, essential for overall bodily function and health.
