The two sides of the plasma membrane have different lipid and protein composition.
The permeability of a biological membrane to a specific polar solute depends primarily on which of the following?
the types of transport proteins in the membrane
The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
In facilitated diffusion, transport proteins provide a hydrophobic route for the solute to cross the membrane.
Actually should be, "In facilitated diffusion, transport proteins provide a hydrophillic route for the solute to cross the membrane."
The movement of glucose into a cell against a concentration gradient is most likely to be accomplished by which of the following?
