the corresponding relationship between cytosolic free ca2+ concentration and the amounts of calcium in the mitochondria and endoplasmic reticulum was investigated in isolated river cells over a range of cellular ca2+ contents by using a nondisruptive technique based on the selective release of calcium from mitochondrial and total cellular pools by addition of carbonyl cyanide p-trifluoromethoxyphenylhydrazone and a23187 , respectively .
