Section A: Biological Molecules (Questions 1–50)
1. Which of the following is a monosaccharide?
A. Sucrose
B. Glucose
C. Maltose
D. Glycogen
Answer: B
Explanation: Glucose is a monosaccharide (single sugar unit). Sucrose and maltose are
disaccharides, and glycogen is a polysaccharide.
Reference: AQA Specification 3.1.2; BIOZONE AQA Biology ALevel 1/AS, Chapter 2.
,2. In a condensation reaction, what is removed to form a glycosidic bond between two
monosaccharides?
A. Carbon dioxide
B. Water
C. Oxygen
D. Hydrogen
Answer: B
Explanation: Condensation reactions between monosaccharides remove a molecule of
water to form a glycosidic bond.
Reference: AQA Specification 3.1.2.
3. Which polysaccharide is the main storage carbohydrate in plant cells?
A. Glycogen
B. Cellulose
C. Starch
D. Chitin
Answer: C
Explanation: Starch is the storage polysaccharide in plants. Glycogen is stored in animals,
and cellulose is structural.
Reference: AQA Specification 3.1.2.
, 4. The structure of cellulose differs from starch because cellulose:
A. Is branched
B. Contains βglucose
C. Is a monosaccharide
D. Contains αglucose
Answer: B
Explanation: Cellulose is composed of βglucose monomers, forming straight chains with
hydrogen bonds. Starch is made of αglucose.
Reference: BIOZONE AQA Biology ALevel 1/AS, Chapter 2.
5. Which test is used to detect the presence of starch?
A. Benedict's test
B. Iodine test
C. Biuret test
D. Emulsion test
Answer: B
Explanation: Iodine solution turns blueblack in the presence of starch. Benedict's tests for
reducing sugars.
