In cellular biology, pinocytosis, otherwise known as fluid endocytosis and bulk-phase pinocytosis, is a mode of endocytosis in which small molecules dissolved in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in their containment within a small vesicle inside the cell.
Mar 26, 2019 · Pinocytosis Definition. Pinocytosis is the method by which a cell absorbs small particles outside the cell and brings them inside. The word pinocytosis comes from the Greek for “cell drinking”.
Jun 30, 2022 · Pinocytosis is an active, energy consuming process where extracellular fluid and solutes are taken up into a cell via small vesicles. It is a type of endocytosis, which refers to the uptake of substances by a cell. Phagocytosis and receptor-mediated endocytosis are other types of endocytosis.
pinocytosis, a process by which liquid droplets are ingested by living cells. Pinocytosis is one type of endocytosis, the general process by which cells engulf external substances, gathering them into special membrane-bound vesicles contained within the cell.
Apr 24, 2024 · In pinocytosis, cells “drink” fluids and dissolved molecules by closing pockets in the cell membrane. Pinocytosis, like phagocytosis, is a way that cells take in materials from outside the cell. But, the vesicles formed by pinocytosis are much smaller than those in phagocytosis.
Aug 3, 2023 · Pinocytosis is a type of endocytosis involved in the transport of particles sized 0.5 µm or less. Process of intake. Phagocytosis involves the formation of pseudopodia (false feet) for the intake of molecules. Pinocytosis intakes the particles via invagination and formation of pockets in the cell membrane.
Mar 11, 2019 · 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.
Pinocytosis is a form of endocytosis involving fluids containing small solutes. In humans this process occurs in cells lining the small intestine and is used primarily for absorption of fat droplets.
Feb 17, 2023 · Pinocytosis, also known as fluid endocytosis, fluid-phase endocytosis, and bulk-phase pinocytosis, is defined as the process where a cell ingests tiny particles suspended in the extracellular fluid by forming an endocytic vesicle called a pinosome.
Pinocytosis (cell drinking) describes the internalization of extracellular fluid and small macromolecules by means of small vesicles. Phagocytosis (cell eating) describes the ingestion of large particles such as cell debris and whole microorganisms by means of large vesicles.
