What is the differece between passive and active transport?

Answer 1

Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell.

ACTIVE TRANSPORT REQUIRES ENERGY.

Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell.

PASSIVE TRANSPORT REQUIRES NO ENERGY.

Answer 2

Passive transport is like diffusion in that particles move across the concentration gradient (from high concentration to low concentration), but active transport it is the movement of particles against the concentration gradient (from low concentration to high concentration).

In the passive transport energy is not needed, but in active transport energy is needed.

Answer 3

Passive transport is a type of diffusion in which no energy is required for it to occur. A common example includes osmosis. On the other hand, active transport does require energy for diffusion to occur. An example includes the diffusion of Cl- ions.

Answer 4

Passive transport does not require energy input from the cell, relying on concentration gradients to move substances across the cell membrane. Active transport, on the other hand, requires energy usually in the form of ATP to move substances against their concentration gradient.
