Plz me
which of the following are types of active transport? (1) the sodium-potassium pump, (2) exocytosis (3)endocytosis (4) osmosis
a. 1 only
b. 2 and 3
c. 1,2, and 3
d.1,2,3, and 4

The correct option is C) 1,2 and 3

Explanation:

Sodium- Potassium pump: Sodium- potassium pump uses ATP to move sodium and potassium ions in opposite directions against the concentration gradient. In one pump, three sodium ions move outside the cell whereas two potassium ions move inside the cell.

Exocytosis: Exocytosis can be described as a form of active transport in which  molecules move out of a cell.

Endocytosis: Endocytosis can be described as a process which utilizes ATP to transport molecules inside a cell.

answer: that would be cheating
