Quizplus · Accepted Answer

The diagram shows that the rate of diffusion increases as the concentration of glucose molecules increases. This is because carrier proteins can only transport a certain number of molecules at a time, so higher concentrations of glucose will lead to more molecules being transported per unit time. Decreasing the number of glucose molecules, lowering the temperature, or raising the pH will all decrease the rate of diffusion.
