摘要: SYNOPSIS. Tetrahymena pyriformis is an exceptionally useful subject for studying metabolic interrelationships among intracellular membranes. Its advantages include the striking differences in lipid composition cell's various functionally distinct membrane systems, indicating a pronounced specificity at sites. The magnitude of these permits analysis mechanisms underlying specificity. Even more valuable unique physical isolation ciliate surface membranes from cytoplasm cell. In contrast to almost immediate equilibration newly made lipids with preexisting found most cells, have turnover slow enough be conveniently analyzed. Finally, well-studied responses such physiological stresses as heat and starvation may used evaluate effects environmental factors on formation.
