Answer:
They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
Explanation:
The cell membranes are semi-permeable as they have molecules that can diffuse from the lipid layer and causes movement.
The internal mitochondrial membrane is nearly impermeable to HCO3- however extraordinarily permeable to CO2. Since fuel online channels are absent, this membrane constitutes a completely unique instance of a membrane of very excessive fuel online permeability because of its extraordinarily low content material of cholesterol.
Why is the membrane selectively permeable?
Selectively permeable due to the fact materials do now no longer go it indiscriminately. Some molecules, consisting of hydrocarbons and oxygen can go through the membrane. Many huge molecules (consisting of glucose and different sugars) cannot. Water can skip thru among the lipids.
Thus it is clear that it can be the cell membrane and mitochondrial membrane selectively permeable to gases.
