<span>An essential functional group involved in cellular energy transfer is the phosphate group.
It is important because it is charged and can release H+ ions into the solution. This makes the group highly acidic, which is important when it comes to the transfer of energy within a cell. Apart from the phosphate group, hydroxyl, carbonyl, amino, and other are also important.</span>
A cell membrane is compared to a window screen because of its translucent properties. Like it allows oxygen to come through or it resists invader who tries to come into the cell.
