INTRACELLULAR TRANSPORT IN THE AMOEBA CHAOS CHAOS 1

摘要: Publisher Summary This chapter presents the features of membrane uptake and intracellular transformation in giant amoeba Chaos chaos, describes what is known about system as a whole relation to ionic osmotic regulation during normal growth. In both pinocytosis phagocytosis depend upon same fundamental mechanisms, vesicles formed processes undergo apparently identical transformations within cytoplasm. The rate at which cycle operates not fixed but varies greatly according physiological state cell. fasting cells under environmental conditions, turnover surface occurs only very low even though are actively moving continually changing shape. A stimulus coat by suitable food organism, or application any variety cationic-inducing substances—including small cations appropriate concentrations, positively charged proteins, dyes, colloidal particles—sets off active process engulfment. Pinocytosis channels cups formed, continuity vesicle with broken, reestablished seems be an instantaneous reaction.
