Kinetic energy and the energy is lost when the ball is thrown.
The correct answer is "active transport is ATP dependent whereas in passive transport molecules use kinetic energy to move across the membrane." in active transport cells use molecules embedded on the cell membrane called carriers in the presence of energy. cells use energy and carriers because molecules must move against concentrated gradient inside the cell. on the hand, passive transport is a process by which molecules move from the region of high concentration to the region of low concentration across plasma membrane until balance is obtained on both sides of the membrane. once equilibrium has been achieved in passive transport the movement of molecules stops.
