Ion transport
Ion transport refers to the movement of charged particles, or ions, across cell membranes, which is essential for various biological processes. Cells use specialized proteins called ion channels and pumps to regulate the concentration of ions like sodium, potassium, calcium, and chloride. This transport is vital for functions such as nerve signaling, muscle contraction, and maintaining the body's fluid balance. By actively or passively moving ions in and out of cells, organisms can create electrical signals and maintain homeostasis, ensuring that bodily systems work efficiently.
