Answer:
Water channel proteins help molecules move through a cell membrane.
Answer:
Selective permeability is a property of a cell membrane that allows it to control which molecules can pass (moving into and out of the cell) through the pores of the membrane
Explanation:
The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose, <u>Celluloso </u> and other sugars) cannot. Water can pass through between the lipids.
