What does the cell membrane control?
The cell membrane controls the movement of substances in and out of the cell.
A lipid bilayer with embedded proteins makes up the cell membrane, which is semi-permeable because certain substances, like glucose or proteins, cannot pass through it and must instead be controlled by simple diffusion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
