Final answer:
Carbohydrates, proteins, and nucleic acids are large molecules built from smaller molecules through dehydration reactions. Proteins are polymers of amino acids and play a crucial role in living organisms. Nucleic acids, such as DNA and RNA, are polymers made up of nucleotides and are involved in storing and transmitting genetic information.
Step-by-step explanation:
Carbohydrates, proteins, and nucleic acids are large molecules (macromolecules) built from smaller molecules (monomers) through dehydration reactions. In a dehydration reaction, water is removed as two monomers are joined together.
Proteins are polymers of amino acids, which are monomers that have an amine functional group and a carboxylic acid functional group. They play a crucial role in living organisms.
Nucleic acids, such as DNA and RNA, are also polymers. They are made up of smaller units called nucleotides. Nucleic acids are involved in storing and transmitting genetic information.
