Answer:
Protein—amino acids; Carbohydrates—monosaccharides; Nucleic acids—nucleotides
Step-by-step explanation:
Proteins are macromolecules formed by one or more polypeptides (amino acid polymers) which are uniquely arranged. They all consist of carbon, hydrogen, oxygen, nitrogen and sulfur. The presence of phosphorus in these macromolecules is rare.
Carbohydrates are important biomolecules, also known as carbohydrates, glycides, or sugars, formed primarily by monosaccharides. They are the most abundant biomolecules in nature and most have the following general formula: (CH2O)n .
Nucleic acids are giant molecules (macromolecules), formed by smaller monomeric units known as nucleotides. They are known as DNA and RNA.
