Diffusion

Detailed explanation-1: -Perfume is sprayed in one part of a room, yet soon it diffuses so that you can smell it everywhere.
Detailed explanation-2: -An excellent example of facilitated diffusion is the transport ofd-glucose into skeletal muscle and adipose cells by theGLUT4 transporter. Glucose transport can proceed as long as the blood concentration of glucose is higher than the intracellular concentration of glucose and as long as the carriers are not saturated.
Detailed explanation-3: -Examples of Diffusion: Examples of diffusion include perfume filling a whole room and the movement of small molecules across a cell membrane.
Detailed explanation-4: -If you spray air freshener in one corner of a room, it will eventually diffuse to all parts of the room, because of the random collision of air molecules.
