Question

The production, or synthesis, of proteins, fats, and carbohydrates involves the

Answer 1

formation of covalent bonds between subunits by dehydration (condensation) reactions — i.e., water is removed as monomers are joined. These anabolic reactions require enzymes and input of energy (ATP). For example: peptide bonds (amino acids), ester bonds (glycerol + fatty acids), and glycosidic bonds (monosaccharides) are all formed by condensation with release of water.
