Carbohydrates, proteins and nucleic acids are polymers that are formed from monomers. which of the following set of statements accurately describe the process of building a polymer and breaking it down
a. Building a polymer involves the dehydration synthesis reaction, where monomers are joined together by removing a water molecule. Breaking down a polymer involves hydrolysis, where water is added to break apart the polymer into its monomer units.

b. Building a polymer involves the formation of covalent bonds between monomers to create a long chain. Breaking down a polymer involves the cleavage of these covalent bonds to release individual monomer units.

c. Building a polymer involves the use of enzymes to catalyze the formation of covalent bonds between monomers. Breaking down a polymer also involves the use of enzymes to catalyze the hydrolysis reaction that breaks apart the polymer.

d. Building a polymer involves the input of energy to drive the dehydration synthesis reaction. Breaking down a polymer involves the release of energy as the hydrolysis reaction releases the stored energy within the polymer.
