Examples Metal ions, such as Na+, K+, Mg2+, or Ca2+, require ion pumps or ion channels to cross membranes and distribute through the body The pump for sodium and potassium is called sodium-potassium pump or Na +/K+-ATPase In the epithelial cells of the stomach, gastric acid is produced by hydrogen potassium ATPase, an electrogenic pump[citation needed] Water, ethanol, and chloroform exemplify simple molecules that do NOT require active transport to cross a membrane.
