Active transport requires energy; passive transport does not.
The concentration gradient is a passive force in cellular transport processes.
Exocytosis is an active process in cellular transport.
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
Active transport requires energy; passive transport does not.
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
The concentration gradient is a passive force in cellular transport processes.
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Exocytosis is an active process in cellular transport.
Passive transport... the opposite of active transport.
Passive transport is the cellular transport mechanism. This all depends on the blood pressure.

Active transport requires energy; passive transport does not.
The 2 transporters of cellular energy are passive and active transport.
Active transport requires energy, passive transport does not.
Active transport requires energy (ATP, GTP, etc) to work against the electrochemical gradient. Passive transport works with the electrochemical gradient and does not require energy. (Think diffusion)
