Below are three examples of chemical reactions in which biomolecules are synthesized and degraded. For each example, decide which side of the chemical equation represents monomers and which side represents polymers. Then, decide which direction arrow represents a dehydration reaction and which represents a hydrolysis reaction. Labels will be used more than once.
