Q. Which of the following protein - sugar pair is present in milk
✅ Correct Answer: (A)
Casein, Lactose
Explanation:
Milk contains casein as its primary protein and lactose as its main sugar.
- Casein → A major milk protein that provides essential amino acids.
- Lactose → A disaccharide sugar found in milk, made up of glucose and galactose.
Why are the other options incorrect?
- (B) Albumin, Glucose → ❌ Albumin is found in blood, not milk. Milk sugar is lactose, not glucose.
- (C) Ferritin, Maltose → ❌ Ferritin is an iron-storage protein, and maltose is not found in milk.
- (D) Casein, Sucrose → ❌ Milk contains lactose, not sucrose.
Thus, the correct protein-sugar pair in milk is Casein and Lactose.
