Stock Photo #4128R-33838, Calcium pumping ATPase enzyme. Molecular model of the ATPase enzyme that pumps calcium in and out of muscle cells and controls muscle contractions. The name ATPase refers to this enzyme's ability to break up the ATP (adenosine triphosphate) molecule and release energy. This ATPase uses the energy to pump calcium ions in and out of muscle cells, and is found in muscle cell membranes. Calcium ions are central to the process of muscle contraction.
