biolgist concludes that a molecule moves across cell membrane by facilitated diffusion because the molecule is small, polar and can accumulate inside cells even when its concentration inside the cell initially is higher that it is outside the cell and they use up more energy when the molecule is present in the environment around the cells than when it is not present. Agree or disagree? why or why not? confused....thanks for your help
