Glucose is a molecule that can move across the cell membrane. if the concentration of glucose is higher inside the cell than outside the cell, then what will happen by the process of diffusion? a. glucose molecules will disappear by diffusion. b. glucose molecules will diffuse out of the cell. c. glucose molecules will stay where they are. d. glucose molecules will diffuse into the cell.

The right answer is B.Glucose molecules will diffuse out of the cell.

Diffusion refers to the natural tendency of a system to homogenize the concentrations of chemical species within it. It is an irreversible transport phenomenon that results in the migration of chemical species into a medium. Under the effect of the thermal agitation a displacement of the constituents of the zones of high concentration towards those of low concentration is observed. From a phenomenological point of view, and in the first order, this phenomenon is governed by a law of Fick.
