Select the statements that are true. Question 1 options: CO2 and O2 are water-soluble molecules that diffuse freely across cell membranes. The differences in permeability between artificial lipid bilayers and cell membranes arise from variations in phospholipid content. Transporters are similar to channels, except that they are larger, allowing folded proteins as well as smaller organic molecules to pass through them. Cells expend energy in the form of ATP hydrolysis so as to maintain ion concentrations that differ from those found outside the cell.
