求翻译：16. A rise in the intracellular Ca2+ concentration causes muscle cells to contract. In addition to an ATP-driven Ca2+ pump, heart muscle cells, which contract quickly and regularly, have an antiporter that exchanges Ca2+ for extracellular Na+ across the plasma membrane. This antiporter rapidly pumps most of the enterin是什么意思？ 待解决
