uses ATP |
|
|
Term
|
Definition
endocytosis
Vesicle formation brings macromolecules into the cell
uses ATP |
|
|
Term
|
Definition
Substances are moved into cell from environment
makes vesicle and uses ATP
2 types:phagocytosis or pinocytosis |
|
|
Term
| How does exocytosis differ from endocytosis? |
|
Definition
| Exocytosis is when vesicle's contents are sent outside of cell. Endocytosis takes stuff into the cell |
