STA1510 Assignment 3 (COMPLETE ANSWERS) Semester 2
2025 - Pass With Distinction Guaranteed
Organic Molecules - ANSWER:Molecules containing carbon, essential for life
Macromolecules - ANSWER:Large molecules composed of carbohydrates, lipids, proteins, and nucleic
acids. Nucleic acids are not polymers. Carbohydrates are made of monosaccharides, lipids of fatty
acids, and proteins of amino acids.
Dehydration Reaction - ANSWER:Chemical process that removes water molecules to form new bonds
Hydrolysis - ANSWER:Chemical process that breaks down compounds by adding water
Amino Acid Structure - ANSWER:Molecules containing carbon, hydrogen, oxygen, and nitrogen. The
properties are determined by the side chain (R group)
Protein Denaturation - ANSWER:Disruption of a protein's structure caused by changes in pH,
temperature, or other factors
DNA Bases - ANSWER:The four nitrogenous bases in DNA: adenine, cytosine, guanine, and thymine
Lipid Functions - ANSWER:Lipids serve as insulation and energy storage in organisms
Protein Structure Levels - ANSWER:Primary structure: sequence of amino acids, secondary structure:
arrangement of polypeptide chains, tertiary structure: 3-D folding, quaternary structure: interaction
of multiple polypeptide chains
