{3.png}
Choose the correct answer from the options given below:

• A. A- I, B-IV, C-II, D-III
• B. A-II, B-III, C-I, D-IV
• C. A-III, B-II, C-IV, D-I
• D. A-IV, B-III, C-I, D-II

Hint:

Milk Protein Matches:
LP System = Cold sterilization
Xanthine oxidase = Cow milk MFGM
Lactoferrin = Red iron-binding glycoprotein
Vitamin B12/Folate binders = Mammary transport.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Biochemical, nutritional, and antimicrobial systems in bovine milk.

Step 2: Detailed Explanation:
Matching milk constituents and enzymatic systems in List I with descriptions in List II:
- A. LP System (Lactoperoxidase System): A natural antibacterial preservation system (Lactoperoxidase $+$ $\text{SCN}^-$ $+$ $\text{H}_2\text{O}_2$) utilized as an alternative to thermal preservation for IV. Cold sterilization preservation of raw milk.
- B. Xanthine Oxidase: A major metalloflavoprotein enzyme abundant on the milk fat globule membrane (MFGM) of III. Cow milk.
- C. Lactoferrin: An iron-binding non-heme I. Red glycoprotein ($80\text{ kDa}$) providing broad bacteriostatic protection.
- D. Vitamin B12 and Folate Binding Proteins: Specific minor whey glycoproteins involved in micronutrient transport and II. Mammary gland development neonatal intestinal delivery.
Matching sequence: A-IV, B-III, C-I, D-II.

Step 3: Final Answer:
Therefore, the correct matching is A-IV, B-III, C-I, D-II, corresponding to option (D).
