Difference between endocytosis and exocytosis (endocytosis vs exocytosis)
Endocytosis is a cellular process by which cells internalize substances from their external environment.
Exocytosis is a type of process, in which involves the movement of materials from the inside of a cell to the exterior of the cell by the use of energy.
What is the difference between endocytosis and exocytosis?
Endocytosis is a cellular process by which cells internalize substances from their external environment.
Exocytosis is a type of process, in which involves the movement of materials from the inside of a cell to the exterior of the cell by the use of energy.
Topic
Endocytosis
Exocytosis
Definition
The process by which cells actively transport substances into a cell by engulfing them in a vesicle is known as Endocytosis.
The Process by which cells actively expel molecules out of the cell into the extracellular fluid is known as Exocytosis.
Function
Helps to absorb nutrients for efficient cellular functioning and eliminate pathogens and old or damaged cells.
Facilitates communication between cells, repairs cell membrane, and eliminates toxins and waste products.
Mechanism
During endocytosis, an endocytic vesicle is formed surrounding the foreign substance, which is either a solid or a liquid.
During exocytosis, the vesicle containing the waste is fused with the plasma membrane in order to eliminate its contents.
Pathway
Occurs over three pathways – phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Occurs through three pathways – regulated, constitutive, and fusion of vesicles with lysosomes
Vesicles
A vesicle is formed around the foreign substance
Fused with the plasma membrane
Vesicles formation
Vesicle is formed from cell membrane. It then gets into the cytoplasm.
Vesicle is formed in the Golgi apparatus. It then fuses with the cell membrane.
Type of vesicle formed
Like phagosomes
Secretory Vesicles
Size of Cell membrane
It Decreases the size of the cell membrane.
It Increases the size of the cell membrane.
Examples
Engulfing bacteria by phagocytes is an example for endocytosis.
Releasing of hormones out of the cell is an example for exocytosis.
