Large biological molecules are synthesized by removing a) covalent bonds. b) water. c) carbon. d) oxygen. e) peptides.

The correct answer is: B) water

Large molecules or macromolecules are necessary for the functioning of an organism and can be classified into four main types: proteins, lipids, nucleic acids and sugars (carbohydrates). All of them are polymers, meaning that are composed of many basic units (monomers) linked by different types of bonds into a functional structure.

Synthesis of these molecules is done through the dehydration (or condensation) reactions, which means that hydrogen (H) from one monomer combines with the hydroxyl group (OH) from another monomer releasing a molecule of water (H2O). Monomers linked via dehydration synthesis reactions share electrons and form covalent bonds.
