细胞内pH值的主动调控

Respir Physiol. 1978 Apr;33(1):59-62. doi: 10.1016/0034-5687(78)90084-1.

When the interior of a squid giant axon is loaded with acid, the cell responds by extruding that acid in an energy-requiring process. Our results indicate that this acid extrusion is accomplished by exchanging external HCO3- for internal Cl- at the expense of ATP.

当鱿鱼巨轴突内部充满酸时，细胞会通过一个需要能量的过程将该酸排出以做出反应。我们的结果表明，这种酸的排出是通过用外部的HCO3-交换内部的Cl-来实现的，这一过程以消耗ATP为代价。
