Using carbohydrates and lipids in energy storage
ADVANTAGES OF CARBOHYDRATESADVANTAGES OF LIPIDS
More easily digested than lipids so the energy stored by them can be released more rapidlyContain more energy per gram than carbohydrates so stores of lipids are lighter than stores of carbohydrates that contain the same amount of energy
Soluble in water so are easier to transport to and from the storeInsoluble in water, so they do not cause problems with osmosis in cells
