Sodium-calcium exchanger

（重定向自Sodium calcium exchanger）

The sodium-calcium exchanger (often denoted Na/Ca exchanger, NCX, or exchange protein) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na) by allowing Na to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca). The NCX removes a single calcium ion in exchange for the import of three sodium ions. The exchanger exists in many different cell types and animal species. The NCX is considered one of the most important cellular mechanisms for removing Ca.

单词	Sodium calcium exchanger
释义	Sodium calcium exchanger 原声例句 Osmosis-泌尿 So calcium flows in through these channels, and to prevent calcium levels from getting too high, cells kick excess calcium right back out with ATP-dependent calcium pumps as well as sodium calcium exchangers. 所以，钙离子通过这些通道流入细胞内，但为防止细胞内的钙离子浓度过高，细胞使用依赖于ATP的钙离子泵、钠钙交换通道将多余的钙离子排出细胞。英语百科 Sodium-calcium exchanger （重定向自Sodium calcium exchanger） The sodium-calcium exchanger (often denoted Na/Ca exchanger, NCX, or exchange protein) is an antiporter membrane protein that removes calcium from cells.
