Meaning of Pinocytosis
What is Pinocytosis:
Pinocytosis is the process by which the cell ingests or transports liquids that are on the outside inside its cell membrane.
In biology, it is known as pinocytosis to the way in which the cell membrane envelops liquids that are on the outside of the cell towards its interior.
In this sense, pinocytosis is also commonly known as the process in which the cell drinks. The word derives from the Greek, composed of the word Pine tree indicating "drink."
The cell membrane is composed of a phospholipid bilayer. Pinocytosis occurs when the membrane begins to surround fluids that are outside the cell until it detaches from the original membrane and into the cell itself.
The sphere that forms around the fluid is known as a vesicle. Vesicles are compartments derived from the cell membrane found within cells.
It is still unknown how cells manage to distinguish what to transport inside them and what not. In addition, the process in which the cell membrane surrounds external objects (phagocytosis) and liquids (pinocytosis) is also being studied, although it is suspected that the cell's cytoskeleton may be involved in these processes.
In addition to cells, pinocytosis is also a form of food for living beings that belong to the fungi Kingdom.
Pinocytosis and endocytosis
Pinocytosis is one of the two types of endocytosis. Endocytosis is the incorporation or transport of objects of high molecular mass into the cell.
Pinocytosis is the transport or intake of fluids by the cell and phagocytosis, the other type of endocytosis is the incorporation of solids.
Pinocytosis and phagocytosis
Pinocytosis and phagocytosis are the 2 types of endocytosis of cells. Endocytosis is also known as mass transport, as it incorporates objects of higher molecular mass, such as bacteria.
In this sense, phagocytosis is known as the way the cell eats, being that etymologically, phage means in Greek to eat. The compartment that the cell membrane incorporates in phagocytosis is called the digestive vacuole.
Pinocytosis and the Kingdom fungi
Organisms that belong to the Kingdom fungi, also known as the Kingdom of fungi, are characterized by using pinocytosis and phagocytosis to feed.
During the process, the beings of the fungi Kingdom usually excrete enzymes capable of breaking down macromolecules until they are small enough to pass through the outer membrane of the fungus.
