Question

Does simple diffusion require ATP energy?

Answer 1

Simple diffusion:

1. Simple diffusion is the passage of molecules through a cell membrane without the use of channels created by integral membrane proteins.
2. Simple diffusion does not necessitate the use of energy; however, assisted diffusion
3. Simple diffusion can only transfer materials in the direction of a concentration gradient; assisted diffusion can move materials in both directions.
4. Simple diffusion does not necessitate the use of ATP energy.
