Monomers are linked into
Polymers are broken down to monomers by ________, which involves the ________ of a water molecule.
Introduction: A biomolecule refers to the molecule and ions present in organisms. Biological molecules are necessary to carry out biological processes such as morphogenesis, cell division, and development. Polymers are long molecules formed by the polymerization of similar small repeating units called monomers.
Answer to Problem 1IQ
Correct answer: “Monomers are linked into polymers by dehydration reaction, which involve the removal of water molecule. Polymers are broken down to monomers by hydrolysis which involves the addition of a water molecule.”
Explanation of Solution
Dehydration reaction is the universal process required for building polymers. The linking process of every two monomers requires dehydration reaction, which is the removal of a water (H2O) molecule. Hence, the depolymerization reaction means that water molecules need to be added to break a polymer into monomers. This process is known as hydrolysis. In a hydrolysis reaction, one water molecule is required to break the bond between two monomers. It involves by attaching a hydroxyl group (-OH) to one monomer and a hydrogen atom (-H) to another monomer.
