当肌浆小泡被破坏或渗漏时，肌浆小泡中atp支持的钙积累就会被消除。天然肌质膜和渗漏肌质膜的特点是对钙具有高的内在亲和力，不依赖于ATP。当细胞膜被剥夺了运输三磷酸腺苷酶活性所必需的磷脂时，钙结合位点的数量和它们对钙的亲和力都不会受到影响。
ATP-Supported calcium accumulation of sarcoplasmic vesicles is abolished when the vesicles are disrupted or made leaky. The native as well as the leaky sarcoplasmic membranes are characterized by a high intrinsic affinity for calcium which does not depend on ATP. Neither the number of the calcium binding sites nor their affinity for calcium is affected when the membranes are deprived of the phospholipids which are essential for the activity of the transport ATPase.
