Difference Between Exocytosis And Endocytosis

There are four types of transport processes in a cell – diffusion, active transport, osmosis and dynamic transport. Two types of multiple transport processes are known as exocytosis and endocytosis.

They transport large particles out of the cell across the plasma membrane. Exocytosis is the process by which cells move unwanted material out of the cell and endocytosis moves large particles that cannot enter the cell across the non-polar membrane.

Difference Between Exocytosis And Endocytosis

Endocytosis allows the cell to take in nutrients and exocytosis removes waste products from the cell.

What is Exocytosis?

The process by which cells move unwanted substances out of the cell is known as exocytosis. Materials transported in this system are waste products such as indigestible residues, materials necessary for the formation of cell walls. Such materials are packed in bundles and oriented towards the plasma membrane.

When these vesicles come into contact with the plasma membrane, they release the debris into the external environment. They transport proteins and polysaccharides into the cell. To attract pollinators, plants use exocytosis to release nectar.

What is Endocytosis?

Endocytosis is the process by which a substance must enter a cell surrounded by part of the plasma membrane. It is the movement of macromolecules, polar substances and large particles from the external environment into the cell and cannot enter the cell through the non-polar membrane.

There are four different types of endocytosis. It is involved in the nervous system, signal transduction, and immune responses in pathological conditions. They can be customer-centric or customer-centric.

Define

It helps in the process of eliminating waste in the external environment It helps in the process of intake of substances from the external environment

Constitutive & regulated secretory pathway Pinocytosis and phagocytosis

Vesicle

Fused with the plasma membrane A vesicle is formed around the foreign substance

Type of vesicle formed

Secretory Vesicles Like phagosomes
