Active Transport where atoms are moved from low concentration to high concentration

Term
Transport by vesicles
Definition

[image]

Vesicles that move molecules between locations inside the cell. For example, proteins from the rough Endoplasmic reticulum to the Golgi Aparatus

Term
Receptor-mediated endocytosis
Definition

[image]

 a process by which cells internalize molecules by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being internalized.

Term
Phagocytosis
Definition

the ingestion of bacteria or other material by phagocytes and ameboid protozoans

Term
Pinocytosis
Definition

[image]

the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane 

Term
Exocytosis
Definition

 a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane
