|
In diffusion, molecules move from an area of low concentration to an area of higher concentration.

Detailed explanation-1: -The statement about diffusion that is false is 1) Simple diffusion depends upon specific carrier proteins. Diffusion is a passive process that doesn’t require carrier proteins, but relies on a difference in concentration. Diffusion is the movement of molecules from a greater concentration to a lesser concentration.
Detailed explanation-2: -It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.-CORRECT.
Detailed explanation-3: -During diffusion, substances move from an area of high concentration to an area of low concentration, until the concentration becomes equal throughout a space.
Detailed explanation-4: -Osmosis And Diffusion Definitions Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Detailed explanation-5: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).
