Carbohydrates, Protein, Lipids, and Dna
Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose, and since glucose is a major cellular fuel, starch represents stored energy. The sugar can later be withdrawn by hydrolysis, which breaks the bonds between monomers. Animals, in turn, have
