Pinocytosis - Wikipedia
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.
Pinocytosis - Definition and Examples | Biology Dictionary
2019年3月26日 · 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”.
Pinocytosis: What Is It, How It Occurs, and More | Osmosis
2022年6月30日 · Pinocytosis is a cellular process that requires substantial energy in the form of adenosine triphosphate (ATP) and is a form of endocytosis, a general process by which substances are brought into a cell.
Pinocytosis – Definition, Process, & Steps with Examples
2023年2月17日 · 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 | Cellular Uptake, Endocytosis & Vesicles | Britannica
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.
Pinocytosis – Definition and Functions - Science Notes and Projects
2024年4月24日 · 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 …
Phagocytosis vs Pinocytosis: Definition and Function
2022年3月21日 · While phagocytosis involves the ingestion of solid material, pinocytosis is the ingestion of surrounding fluid(s). This type of endocytosis allows a cell to engulf dissolved substances that bind to the cell membrane prior to internalization.
Pinocytosis - an overview | ScienceDirect Topics
Pinocytosis is a form of endocytosis involving fluids containing many solutes. In humans, this process occurs in cells lining the small intestine and is used primarily for absorption of fat droplets.
Pinocytosis - Definition and Examples - Biology Online Dictionary
2022年6月16日 · Pinocytosis (biology definition): a biological process of taking in fluid together with its contents into the cell by forming narrow channels through its membrane that pinch off into vesicles, and fuse with lysosomes that hydrolyze or break down contents.
Pinocytosis- definition, steps, types, examples, (vs phagocytosis)
2023年8月3日 · Pinocytosis is a form of active transport that plays a vital role in cellular processes like nutrients uptake, excretion of waste materials, and signal transduction. Pinocytosis is utilized by various unicellular organisms for the uptake of nutrients such as certain sugars, most amino acids, organic acids, and many inorganic ions.
