Answer 2

Simple Diffusion

Simple diffusion is defined as the movement of molecules or ions from an area of higher concentration to an area of lower concentration, without the need for energy input or the assistance of a transport protein.

In simple diffusion, molecules move down their concentration gradient, which is the difference in concentration between two areas. This process occurs until equilibrium is reached, meaning there is an equal concentration of molecules on both sides of the membrane.

Simple diffusion is a passive process, meaning it does not require the input of energy. It is driven by the random motion of molecules and the tendency of molecules to move from areas of higher concentration to areas of lower concentration, which is known as the concentration gradient.

Simple diffusion plays a crucial role in various biological processes, such as the exchange of gases in the lungs and the movement of nutrients and waste products across cell membranes.
