Simple diffusion is most accurately described by which of the following?

0 votes

 

Solutes are transported across a cell membrane by a carrier in a direction independent of solute concentration.

Simple diffusion is an energy-requiring process.

Solutes must be soluble in the cell membrane, and a concentration gradient must be present in order for any net diffusion to take place.

The process of simple diffusion is independent of temperature and the distance a molecule diffuses.
