Abstract
A significant digitonin-sensitive calcium pool has been shown to exist in Tetrahymena pyriformis cells. In the presence of exogenic energy s ources, calcium, released from the digitonin-sensitive pool, can be ac cumulated by mitochondria or endoplasmic reticulum. The kinetic charac teristics of the mitochondrial and reticulum systems of Ca2+ transport and their sensitivity to various inhibitors were studied.
