The condensation and hydrolysis reactions are equally spontaneous d. Because polymers are energetically more stable and have lower potential energy than monomers 2. How does the structure of an amino acid affect its most common function in cells? a. It can serve a wide variety of functions in the cell because it contains the atoms most commonly found in organisms (C, H, N, and O) b. Because both carboxyl and amino groups are present, polymerization is exergonic. In addition, the presence of a side chain makes the molecule water soluble. c. The presence of carboxyl and amino groups gives it the ability to form peptide bonds, and its side chain gives it unique chemical properties. d. Because each amino acid contains a variety of functional groups, they can participate in a wide variety of chemical reactions. 3.
