both these processes do the transport against the concentration gradient uh no facilitated diffusion doesnt go against the gradient, the similiarity is that they both use carrier protiens
They both serve to transport molecules across cell membranes and both make use of proteins embedded in cell membrane in order to move these molecules. -Estela Mireles
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
