Difference Between Exocytosis And Endocytosis

  • Endocytosis is defined as the process of trapping a particle or substance from the external environment by engulfing it. Endocytosis is of two types viz phagocytosis, also known as cellular eating and pinocytosis, also referred to as cellular drinking.
  • Exocytosis, on the other hand, is described as the process of fusing vesicles with the plasma membrane to release their contents to the external environment of the cell.

The basic difference between Exocytosis And Endocytosis is tabulated below.

Exocytosis vs Endocytosis

Exocytosis Endocytosis
Define
It helps in the process to eliminate waste in the external environment
It helps in the process of intake of substances from the external environment
Occurs
Constitutive & regulated secretory pathway Pinocytosis
Vesicle
Fused with the plasma membrane
A vesicle is formed around the foreign substance
Type of vesicle formed
Secretory Vesicles Like phagosomes
Example
Realizing hormone outside the cell
Engulfing bacteria by phagocytes
