Which phenomena is commonly refered as cell drinking
Answers
Answer:
The term “endocytosis” was coined by Christian deDuve in 1963 to include both the ingestion of large particles (such as bacteria) and the uptake of fluids or macromolecules in small vesicles. The former of these activities is known as phagocytosis (cell eating) and the latter as pinocytosis (cell drinking).
Explanation:
Pinocytosis is a cellular process by which fluids and nutrients are ingested by cells. Also called cell drinking, pinocytosis is a type of endocytosis that involves the inward folding of the cell membrane (plasma membrane) and the formation of membrane-bound, fluid-filled vesicles. These vesicles transport extracellular fluid and dissolved molecules (salts, sugars, etc.) across cells or deposit them in the cytoplasm. Pinocytosis, sometimes referred to as fluid-phase endocytosis, is a continual process that occurs in most cells and a non-specific means of internalizing fluid and dissolved nutrients. Since pinocytosis involves the removal of portions of the cell membrane in the formation of vesicles, this material must be replaced in order for a cell to maintain its size. Membrane material is returned to the membrane surface through exocytosis. Endocytotic and exocytotic processes are regulated and balanced in order to ensure that a cell's size remains relatively constant.
