Please am I correct? Water (H2O), carbon dioxide (CO2), and oxygen (O2) are all quite small molecules, yet they move across cell membranes differently. Both CO2 and O2 passively diffuse across the cell membrane directly while H2O moves across the cell membrane by facilitated diffusion. What can be concluded about these three molecules based on the way they react to the cell membrane? The amount of H2O the cell allows to cross the membrane must be more carefully controlled than the amounts of CO2 or O2. The concentration of H2O is higher outside the cell and the concentrations of CO2 and O2 are higher inside the cell. The H2O molecules are repelled by the lipid tails of the phospholipids, but the CO2 and O2 molecules are not. The H2O molecules are too large to pass between the phospholipids while the molecules of CO2 and O2 are not.
