A biologist conducts an experiment designed to determine whether a particular type of molecule is transported into cells by simple diffusion, facilitated diffusion, or active transport. He collects the following information: (1)The molecule is very small (2)The molecule is polar (3) The molecule can accumulate inside a cell, even when its concentration inside the cell initially is higher than it is outside the cell (4) Cells use up more energy when the molecule is present in the environment around the cells than when it is not present.The biologist concludes that the molecule moves across cell membranes by facilitated diffusion. Do you agree with his conclusion
