Analyze lipid functions

Using the Biomolecules knowledge point, we evaluate the biological roles of lipids. Lipids are hydrophobic macromolecules that serve as highly concentrated energy stores, providing long-term energy storage. They also function as structural components of cell membranes and provide thermal insulation.

Evaluate Question 15 options

• "to provide immunity" is primarily a function of specific proteins (antibodies).
• "to provide short term energy" is the main function of carbohydrates.
• "to provide genetic information" is the function of nucleic acids (DNA and RNA).
• "to provide long term energy and insulate" correctly describes the primary functions of lipids.

Analyze protein monomers

Using the Biomolecules knowledge point, we examine the building blocks of proteins. Proteins are polypeptides made of individual monomeric subunits linked by peptide bonds.

Evaluate Question 16 options

• "monosaccharides (simple sugars)" are the monomers of carbohydrates.
• "nucleotides" are the monomers of nucleic acids.
• "amino acids" are the monomers of proteins.
• "fatty acids" are components of many lipids, not proteins.
