E)the formation of disulphide bridges between monomers

Question

Quizplus · Accepted Answer

The chemical reaction mechanism by which cells make polymers from monomers is through dehydration reactions. During this process, water molecules are removed from the monomers, allowing them to bond covalently and form a polymer. This is how biological molecules like proteins, carbohydrates, and nucleic acids are formed.

Option A, phosphodiester linkages, refers to the specific type of covalent bond found in DNA and RNA molecules, but it does not describe the general mechanism by which cells form polymers.

Option B, hydrolysis, is the opposite of dehydration, where water molecules are added to break apart polymers into their constituent monomers.

Option D, ionic bonding, involves the transfer of electrons between atoms, which is not a common mechanism for forming biological polymers in cells.

Option E, disulphide bridges, are specific covalent bonds formed between certain amino acids in proteins and are not involved in the general mechanism of polymer formation.
