What best explains the relationship between structure and function of the cell membrane? the single layer membrane surrounding the outside of the cell allows for the easy removal of waste. the lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell. the fluid inside the membrane buffers the chemical reactions taking place inside the cell. the lipids forming the membrane provide energy for protein synthesis.

The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell.

Explanation:

The cell membrane is a biological membrane that separates the interior of cells from the environment outside of it. This protects the cell from the environment outside of it. It also plays an important role in what gets in and out of the cell. As the membrane is made up of lipids and proteins, it is able to control the movement of substances in and out of cells and organelles.
