Down concentration gradient meaning
WebDiffusing down the gradient means that through the random motion of small molecules, some of the molecules in the high concentration region will end up in the formerly low concentration region. Explain why facilitated diffusion does not require energy from a cell. The solute can move "downhill," from regions of higher to lower concentration ...
