Vesicular Transport

What is vesicular transport?

A mechanism that moves large particles, droplets of fluid, or numerous particles through the membrane in vesicles.

Types of vesicular transport?

Endocytosis and Exocytosis

What is endocytosis?

The movement of material into a cell within a vesicle (endosomes), requiring ATP.

What is phagocytosis?

A type of endocytosis known as "cell eating," where cells engulf large particles, forming a phagosome that merges with a lysosome.

What are phagosomes and phagolysosomes?

A phagosome is a vesicle that engulfs particles; a phagolysosome is formed when a phagosome fuses with a lysosome.

What is exocytosis?

The process of releasing materials from a cell, requiring ATP.

What substances are commonly secreted via exocytosis?

Digestive enzymes, neurotransmitters, antibodies, and mucus.

Why is vesicular transport important?

It allows cells to take in large molecules and expel waste or signaling molecules, playing a crucial role in immune response and cellular communication.
