Sample Problem

Carbohydrates (Check all that apply)

(A) are polysaccharides

(B) are made from carbons, hydrogens, and oxygens

(C) store energy

(D) are synthesized through peptide bonding

Solution

(A), (B), and (C) are correct. Carbohydrates are made from multiple monosaccharides, so they are also called polysaccharides. They are synthesized through dehydration synthesis just like proteins, but these do not form peptide bonds in carbohydrates (D).
