While simple and easy diffusion and active transport are entry or exit mechanisms for small molecules and ions, large molecules or even particles made up of molecular aggregates are transported through other processes.


This process allows the transport of substances from the extracellular medium through membrane-bound vesicles, which are called endocytosis vesicles or endocytic. These are formed by invagination of the plasma membrane, followed by fusion and separation of a segment thereof.

There are three types of endocytosis:

- Pinocytosis
- Phagocytosis
- Mediated Endocytosis

From now on, we will study each of them.
