Match the type of carbohydrate with its description:

Monosaccharides = Simplest carbs (simple sugars) Polysaccharides = Long chain carbohydrates, used for food storage Disaccharides = Carbohydrates formed due to glycosidic bonds Micromolecule = Another term for monosaccharides Signup and view all the answers

Match the carbohydrate role with its function:

As the body's main source of energy = Glucose As food storage compounds = Polysaccharides Form structural components in plant cells = Long chain carbohydrates Excess consumption results into stored fat = Long chain carbohydrates Signup and view all the answers
