ion channels
Ion channels are specialized proteins in cell membranes that allow charged particles, or ions, to pass in and out of cells. They function like tiny gates, opening or closing in response to signals from the body, such as electrical impulses or specific molecules. This movement of ions is crucial for many biological processes, including nerve signaling, muscle contraction, and maintaining the cell’s overall balance. By regulating the flow of ions, these channels help control various functions, ensuring cells respond appropriately to their environment and communicate effectively with each other.

Ion channels are specialized proteins found in cell membranes that allow charged particles, or ions, to pass in and out of cells. They play a crucial role in various physiological processes, including nerve signaling, muscle contraction, and maintaining the cell's electrical balance. Each ion channel is selective, meaning it only permits specific ions, such as sodium, potassium, calcium, or chloride, to flow through. When ions move through these channels, they can trigger changes in the cell's activity, significantly influencing communication between cells and bodily functions. Disruptions in ion channel function can lead to various health issues.
