Studies of membrane formation in Tetrahymena pyriformis. V. Lipid incorporation into various cellular membranes of stationary phase cells, starving cells, and cells treated with metabolic inhibitors

摘要: The distribution rates of radioactive phospholipids to various membranes Tetrahymena pyriformis are nearly identical in cells experiencing rapid growth, no and starvation-induced shrinkage. Furthermore, neither the inhibition proteins synthesis by cycloheximide nor fatty acid tetralylphenoxyisobutyric altered lipid rates. As recently observed other organisms, insertion into is not coupled protein insertion, reverse situation also seems be true. data best explained postulating a exchange intact lipids as being prime mechanism causing intracellular these molecules.
