Analyze Question 5

The question asks which element, along with a few others, plays a key role in determining the structure and function of macromolecules needed to sustain life. Carbon is the fundamental backbone of all organic macromolecules (carbohydrates, lipids, proteins, and nucleic acids) due to its ability to form four stable covalent bonds.

Analyze Question 6

The question asks for the monomer of lipids. Lipids are typically composed of glycerol and fatty acids. Among the choices provided, fatty acids represent the building blocks (monomers/subunits) of lipids. Nucleotides are monomers of nucleic acids, amino acids are monomers of proteins, and monosaccharides are monomers of carbohydrates.
