3. If O2 is found in high concentration on the outside of a cell: a) energy will be expended to pump it inside the cell. b) it will move inside the cell through a protein channel. c) it will form a shell around the outside of the cell. d) it will passively diffuse out of the cell. e) none of the above e) none of the above Solution e) none of the above O2 would diffuse in through the membrane since it\'s non-polar and small molecule.
