Abstract
- Mitochondria isolated from the ventricles of Cavia porcellus, Mesocricetus auratus, Rattus rattus and Mus musculus accumulate calcium in an energy-linked process. 2. Measurements of the initial velocity of accumulation by dual-wavelength spectrophotometry show species-dependent variation, with Cavia demonstrating the fastest rate and Rattus the slowest rate of accumulation. 3. Total amount of calcium accumulated per unit protein varied in a manner similar to rate of accumulation, with Cavia accumulating the greatest amount of calcium and Rattus the least.
摘要
- 从豚鼠、金黄仓鼠、黑家鼠和小家鼠心室分离出的线粒体，在一个能量关联过程中积累钙。2. 通过双波长分光光度法对积累初始速度的测量显示出种属依赖性变化，豚鼠积累速度最快，黑家鼠积累速度最慢。3. 每单位蛋白质积累的钙总量变化方式与积累速度相似，豚鼠积累的钙量最多，黑家鼠最少。
