Ion transport proteins

Ion transport proteins are specialized molecules embedded in cell membranes that help move ions—charged particles like sodium, potassium, calcium, and chloride—into or out of cells. They maintain the proper balance of ions essential for functions like nerve signals, muscle contractions, and fluid regulation. These proteins can actively transport ions against their concentration gradient using energy, or facilitate their movement along it. By controlling ion flow, they help regulate cell volume, electrical activity, and overall cellular health, making them vital for normal body function.
