Biological macromolecules are polymers that are formed when _ are joined by a _ reaction.
Correct answer: A. Monomers, Dehydration
- A. Monomers, Dehydration
- B. Subunits, Reduction
- C. Multimers, Dehydration
- D. Monomers, Hydrolysis
Explanation
Biological macromolecules are large molecules essential for life, formed from smaller units called monomers. The monomers are linked together through a dehydration reaction, also known as a condensation reaction, where a water molecule is removed during the bonding process. Option A is correct because it accurately describes this process. Option B is incorrect because reduction reactions are not involved in forming macromolecules. Option C is incorrect because it incorrectly uses 'multimers' instead of 'monomers.' Option D is incorrect because hydrolysis is the process of breaking down polymers, not forming them.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
