Q1. ________ Is A Catalyst In The Polymerization Of Milk Proteins.
A. Chymosin
B. Phospholipases
C. Peptidase
D. Transglutaminase (Tgase)
ANSWER – D. Transglutaminase (Tgase)
- Explanation – Tgase (Transglutaminase) Is A Catalyst In The Polymerization Of Milk Proteins That Improves The Characteristics Of Milk Products. Almost All Eukaryotic And Prokaryotic Species Contain The Enzyme. The Use Of The Transglutaminase Enzyme To Crosslink Milk Proteins Resulted In Increased Gel Firmness And Whey Incorporation, Increasing Cottage Cheese Yield.

Q4. Which Of The Following Is Formed When Odd Chain Fatty Acids Undergo Beta-Oxidation?
A. Acetyl CoA
B. Propionyl CoA
C. Malonyl CoA
D. All Of The Above
ANSWER – B. Propionyl CoA
- Explanation– The Oxidation Of Fatty Acids With Double Bonds Necessitates Extra Stages. Similarly, At The Last Thiolysis Stage, Fatty Acids With An Odd Number Of Carbon Atoms Produce Propionyl CoA, Which Must Be Transformed Into A Useful Form By Further Enzyme Processes.

Q5. ________ Is The First Enzyme Reported To Be Found In Milk.
A. Lactoperoxidase
B. Lactase
C. Catalases
D. Amylases
ANSWER: A. Lactoperoxidase
- Explanation: Lactoperoxidase Is A Naturally Occurring Enzyme Found In Raw Milk, Colostrum, And Saliva. It’s The First Time An Enzyme Has Been Discovered In Milk. It’s The Most Heat-Resistant Enzyme There Is. By Oxidizing Thiocyanate In The Presence Of Hydrogen Peroxide, It Has Antimicrobial Action. Lactoperoxidase Is A Bactericidal Enzyme In Milk That Kills Gram-Negative Bacteria.
