If you are interested in the diffusion of glucose instead of oxygen, you get a different diffusion coefficient D, and so the line has a different slope.

Derivation of Fick

WebFick proposed laws governing the diffusion of atoms and molecules, which can be applied to the diffusion processes in metals and alloys. He proposed two laws, the first for steady-state condition and unidirectional flow of atoms and the second law which deals with time dependence of concentration gradient; and the flow of atoms in all directions.
