Question

Pancreas secretes pancreatic juice which contain enzyme that helps in digestion of food. Choose the correct option from the following:

• A. Trypsin digests emulsified fats and lipase digests proteins.
• B. Trypsin digests proteins and lipase digests emulsified fats.
• C. Trypsin and lipase both digests fats.
• D. Trypsin digests proteins and lipase digests carbohydrates.

Hint:

Pancreatic enzymes:

• Trypsin \(\Rightarrow\) Proteins \(\Rightarrow\) Peptides
• Lipase \(\Rightarrow\) Emulsified fats \(\Rightarrow\) Fatty acids + Glycerol
• Amylase \(\Rightarrow\) Starch \(\Rightarrow\) Maltose

Answer 1

The Correct Option is B

Step 1: Understand pancreatic enzymes.
Pancreatic juice contains several digestive enzymes including:

• Trypsin: A protease that digests proteins into peptides.
• Lipase: An enzyme that digests emulsified fats into fatty acids and glycerol.
• Amylase: An enzyme that digests starch into maltose.

Step 2: Analyze each option.

• (A) Trypsin digests emulsified fats and lipase digests proteins: Incorrect. This reverses the functions of trypsin and lipase.
• (B) Trypsin digests proteins and lipase digests emulsified fats: Correct. This correctly states the functions.
• (C) Trypsin and lipase both digests fats: Incorrect. Trypsin digests proteins, not fats.
• (D) Trypsin digests proteins and lipase digests carbohydrates: Incorrect. Lipase digests fats, not carbohydrates. Carbohydrates are digested by amylase.

Final Answer: (B) Trypsin digests proteins and lipase digests emulsified fats.
