Question

endocytosis and exocytosis are forms of active transport. what is active transport? (1 point) the movement of molecules down a concentration gradient from high to low, using energy the movement of molecules down a concentration gradient from high to low, using no energy the movement of molecules up a concentration gradient from low to high, using no energy the movement of molecules up a concentration gradient from low to high, using energy

Explanation:

Active transport is the process where molecules move against their concentration gradient (from low - concentration to high - concentration areas) and this requires energy input.

Answer:

the movement of molecules up a concentration gradient from low to high, using energy
