(D) Transport along the concentration gradient means moving from a region of higher concentration to a region of lower concentration. This process does not require metabolic energy $(ATP)$.Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration.Facilitated diffusion also occurs along the concentration gradient,utilizing membrane proteins to transport molecules without the expenditure of energy.Active transport,on the other hand,occurs against the concentration gradient and requires energy in the form of $ATP$.Therefore,both diffusion and facilitated diffusion occur along the concentration gradient.
