Which of the following statements about Ca 2 + pumps is FALSE?

Calcium pumps, such as the Ca2+ ATPase, actively transport calcium ions from the cytosol into organelles or the extracellular fluid, not from organelles into the cytosol. This helps maintain low cytosolic calcium levels, utilizes ATP (hence ATPase activity), and is a form of primary active transport.
