Does diffusion require ATP?

Understand the Problem

The question is asking whether diffusion, a process by which molecules move from an area of higher concentration to an area of lower concentration, requires energy in the form of ATP. This relates to the distinction between active and passive transport mechanisms in biological systems.

More Information

Diffusion is a passive transport process where molecules move from an area of higher concentration to an area of lower concentration without the use of cellular energy (ATP).

Tips

A common mistake is confusing diffusion with active transport, which does require ATP.
