Question

in what way is active transport opposite to diffusion?

Answer 1

Dear student,

Active transport:

• It is the movement of molecules across a cell membrane against its concentration gradient (from low to high concentration).
• Energy in the form of ATP is required, since the molecules move against the normal flow.

Diffusion:

• It is the overall movement of material from an area of higher concentration to an area of lower concentration.
• It requires no energy
