30 Ιουν 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.
17 Φεβ 2023 · Pinocytosis requires a considerable investment of cellular energy in the form of ATP to run. Therefore, it is an active transport mechanism. Though it is not specific, certain ions or amino acids can trigger the process.
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.
26 Μαρ 2019 · Small particles of substances in the ECF are absorbed into the cell via pinocytosis. It is a process that requires active transport, which means that it requires energy on the part of the cell (as opposed to a process like simple diffusion).
3 Αυγ 2023 · Pinocytosis is not molecule-specific and moves a large number of molecules at one time. ATP utilization: Phagocytosis utilizes or requires more ATP and in turn, more amount of energy. Pinocytosis requires a comparatively lesser number of ATPs. Vesicles formed: Vesicles formed by phagocytosis are termed phagosomes.
Pinocytosis involves a considerable investment of cellular energy in the form of ATP and so is many 1000 times less efficient than RME (see Chapter 17). Also, in sharp contrast to RME, pinocytosis is nonspecific for the substances it accumulates.
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.
