Answer
This statement is misleading. Carbohydrates serve as energy sources and structural components, but they do not inherently increase the rate of reactions. Enzymes typically play this role.
Step 3
C. nucleic acids are made up of chains of amino acids.

Answer
This statement is incorrect. Nucleic acids, such as DNA and RNA, are made up of nucleotide units, not amino acids. Amino acids are the building blocks of proteins.
