Which statement correctly describes the permeability of the cell surface membrane?
- AAn increase in the concentration of cholesterol molecules in the cell surface membrane can increase its permeability to hydrophilic substances.
- BCell surface membrane permeability to large hydrophilic molecules is high and can be increased by membrane transport proteins involved in facilitated diffusion.
- CThe permeability of the cell surface membrane to ions is increased with an increase in the proportion of saturated fatty acids in the phospholipids.
- DWithout the presence of carrier and channel membrane proteins, the cell surface membrane has a low permeability to large polar molecules.
