fatty acids and glycerol dna

1. match the polymer on the left to the macromolecule on the right.

cholesterol protein
enzyme lipid
rna nucleic acid
cellulose carbohydrate

Explanation:

1. Monomers are single - unit molecules that bond together through polymerization reactions to form polymers, which are large - chain molecules.
2. All four classes (proteins, nucleic acids, carbohydrates, lipids) are crucial. For example, nucleic acids (DNA and RNA) carry genetic information; proteins have diverse functions like catalyzing reactions (enzymes), structural support, etc.; carbohydrates provide energy; lipids are important for cell membranes and energy storage. It's hard to say one is the most important as they all work in concert.
3. Fatty acids and glycerol - Lipid; Monosaccharide - Carbohydrate; Nucleotide - Nucleic acid; Amino acid - Protein
4. DNA - Nucleic acid; Enzyme - Protein; Triglyceride - Lipid; Polysaccharide - Carbohydrate
5. Fatty acids and glycerol - Phospholipid; Monosaccharide - Starch; Nucleotide - RNA; Amino acid - Enzyme
6. Fatty acids and glycerol - Triglyceride; Glucose (a monosaccharide) - Glycogen; Nucleotide - DNA; Amino acid - Enzyme
7. Amino acid - Collagen (protein); Monosaccharide - Glycogen; Nucleotide - DNA; Fatty acids and glycerol - Phospholipid
8. Cholesterol - Lipid; Enzyme - Protein; RNA - Nucleic acid; Cellulose - Carbohydrate

Answer:

1. Monomers are the building blocks of polymers. They join together via chemical bonds to form polymers.
2. It's difficult to determine a single most - important class as all are essential for life processes.
3. Fatty acids and glycerol - Lipid; Monosaccharide - Carbohydrate; Nucleotide - Nucleic acid; Amino acid - Protein
