Q. Following statements are related with the diffusion of coloured molecules across a membrane. Select the correct statement, which shows the fastest rate of diffusion?

A) An internal concentration of 15% and external concentration of 10%
B) An internal concentration of 25% and external concentration of 50%
C) An internal concentration of 50% and external concentration of 25%
D) Both (b) and (c) shows fastest rate of diffusion
Explanation

Diffusion process takes place between concentration of molecule solution and it is process, where the movement of molecules occur from a higher concentration to lower concentration, either it is internal or external. Higher the concentration gradient, higher will be the rate of diffusion
