WebMolecules that freely cross cell membranes do so through the process of simple diffusion. That is, they move from a high concentration outside the cell to a lower concentration inside the cell, or vice versa. Carbon dioxide (CO 2) and oxygen (O 2) are both molecules that can move across cell membranes through simple diffusion.
