Active Transport Flashcards
(2 cards)
1
Q
Define active transport
A
Active process: ATP hydrolysis releases phosphate group that binds to carrier protein, causing it to change shape.
Specific carrier proteins transport molecule/ions from area of low concentration to area of higher concentration
2
Q
Define exocytosis and endocytosis
A
Exocytosis: involving bulk transport out of cell
Endocytosis:
-phagocytosis: bulk transport of solids into cell using vesicle
-pinocytosis: bulk transport of liquid into a cell using vesicle
