Pinocytosis

What is pinocytosis

Pinocytosis is the process by which the cell ingests or transports liquids within its cell membrane that are found outside.

In biology, the way in which the cell membrane wraps liquids that are on the outside of the cell towards the inside is known as pinocytosis.

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 which indicates “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 enters the cell itself.

The sphere that forms surrounding the liquid is known as gallbladder. Vesicles are compartments derived from the cell membrane that are found inside 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) continues to be studied, although it is suspected that the cell’s cytoskeleton may be involved in these processes.

In addition to cells, pinocytosis is also a way of feeding living beings that belong to the Fungi Kingdom.

Pinocytosis and endocytosis

Pinocytosis is one of 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 liquids 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 cell endocytosis. Endocytosis is also known as mass transport, since it incorporates objects with higher molecular mass such as bacteria.

In this sense, phagocytosis is known as the way in which the cell eats, and etymologically, phage means to eat in Greek. The compartment that the cell membrane incorporates in phagocytosis is called the digestive vacuole.

Pinocytosis and the Fungal Kingdom

Organisms that belong to the Kingdom fungi, also known as the Fungi Kingdom, are characterized by using pinocytosis and phagocytosis to feed.

During the process, 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.
