Diffusion requires cell energy while active transport does not

Respuesta :

Active transport does diffusion doesn’t

The correct statement concerning diffusion and active transport is - Active transport requires cell energy while diffusion does not.

Active transport is the transport of substances or molecules against the concentration gradient in the cell through the membrane.

  • As it moves against the concentration gradient it requires energy to perform such movement.
  • This process gets energy from the powerhouse of the cell
  • It is a unidirectional movement
  • it is a selective process.

Diffusion is the process where the movement of the solvent takes place according to the concentration gradient. It does not require energy and is a non-selective process.

Thus, the correct answer is - Active transport requires cell energy while diffusion does not.
