Not to answer this question, let's talk about the lipid permeability.
00:05
It says, how many of the following factors would affect the permeability of a cell membrane? remember that the cell membrane is made of a lipid bilayer.
00:13
And the core of this cell membrane is made of lipids.
00:18
And if this is your cell membrane, this lipid membrane is going to be permeable to some substances, and it is not going to be permeable to other substances.
00:27
This is why the cell membrane is a semi -permeable membrane.
00:31
It is going to be permeable, for example, to small molecules, but it is not going to be permeable to big or large molecules.
00:40
So this question says, how many of the following factors would affect the permeability of the cell membrane? option a says the size of the molecules, and this is true, because small molecules are going to be able to cross the cell membrane, while the big molecules are not going to be able to move across the cell membrane...
