INTRODUCTION
This comprehensive CHEM120 Week 6 Laboratory Report assessment is designed to evaluate the student's
understanding of the fundamental concepts of organic and biological chemistry, specifically focusing on
carbohydrates, lipids, proteins, and enzymes. It assesses the application of chemical principles to biological
systems, requiring the synthesis of information across multiple domains. Candidates will be challenged to analyze
the structure and function of biomolecules, understand the relationship between structure and function, and apply
,principles of enzymology. This rigorous assessment mirrors the complexity of laboratory experiments and is
structured to reflect the official CHEM120 examination blueprint.
SECTION ONE
Questions 1–100
Question 1
The general formula for a carbohydrate is:
A. CnH2nOn
B. CnH2nO2n
C. CnH2nO
D. CnH2n+2On
🟢 Correct Answer:
A. CnH2nOn
🔴 RATIONALE:
The general formula for a carbohydrate is CnH2nOn, where n is the number of carbon atoms. For example,
,glucose is C6H12O6. This formula reflects the fact that carbohydrates contain carbon, hydrogen, and oxygen in
a ratio of 1:2:1.
Question 2
Which of the following is a monosaccharide?
A. Sucrose
B. Maltose
C. Glucose
D. Cellulose
🟢 Correct Answer:
C. Glucose
🔴 RATIONALE:
Glucose is a monosaccharide (simple sugar). Sucrose and maltose are disaccharides (composed of two
monosaccharides). Cellulose is a polysaccharide (a polymer of glucose). Monosaccharides are the simplest form
of carbohydrates.
Question 3
The bond that links two monosaccharides together to form a disaccharide is called a:
, A. Peptide bond
B. Glycosidic bond
C. Ester bond
D. Hydrogen bond
🟢 Correct Answer:
B. Glycosidic bond
🔴 RATIONALE:
A glycosidic bond is the covalent bond that links two monosaccharides together to form a disaccharide or
polysaccharide. A peptide bond links amino acids; an ester bond links fatty acids to glycerol; hydrogen bonds
are weak interactions.
Question 4
Which of the following is a reducing sugar?
A. Sucrose
B. Starch
C. Glucose
D. Cellulose
🟢 Correct Answer:
C. Glucose
