Question

Explain the mechanism of Passive and Active transport

Answer 1

in passive transport the ATP is not utilized.
In active transport the ATP is utilized
Ex: Na + / K + pump

Answer 2

Active Transport uses ATP to pump molecules AGAINST/UP the concentration gradient. Transport occurs from a low concentration of solute to high concentration of solute. Requires cellular energy.Movement of molecules DOWN the concentration gradient. It goes from high to low concentration, in order to maintain equilibrium in the cells. Does not require cellular energy.
