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

The pancreas is a crucial organ in the digestive system that secretes pancreatic juice, which contains several enzymes important for digestion. Two of these enzymes are trypsin and lipase, each with a specific function:

1. Trypsin: This enzyme helps in the digestion of proteins. It breaks down proteins into smaller peptides. Trypsin is produced in an inactive form called trypsinogen, which is activated in the small intestine.
2. Lipase: This enzyme is responsible for digesting emulsified fats. It breaks down triglycerides into free fatty acids and glycerol.

Let's analyze the given options to identify the correct answer:

• Option 1: Trypsin digests emulsified fats and lipase digests proteins. (Incorrect: This reverses the roles of the enzymes.)
• Option 2: Trypsin digests proteins and lipase digests emulsified fats. (Correct: This correctly identifies the functions of trypsin and lipase.)
• Option 3: Trypsin and lipase both digest fats. (Incorrect: Trypsin digests proteins, not fats.)
• Option 4: Trypsin digests proteins and lipase digests carbohydrates. (Incorrect: Lipase digests fats, not carbohydrates.)

Thus, the correct option is "Trypsin digests proteins and lipase digests emulsified fats."

Understanding the roles of different digestive enzymes is crucial for comprehending how the body processes and absorbs nutrients from food.
