Select the INCORRECT pair related to digestive glands and their enzymes.

Correct option is A

The correct answer is (a) Salivary gland - trypsin 

Explanation:

The salivary gland secretes saliva, which contains the enzyme salivary amylase (ptyalin), not trypsin. Salivary amylase helps in the digestion of carbohydrates by breaking down starch into maltose.

Trypsin, on the other hand, is secreted by the pancreas as trypsinogen (inactive form), which gets activated in the small intestine and helps in protein digestion.

Information Booster:

Salivary Gland:

• Secretes saliva which contains salivary amylase (ptyalin).
• Helps in the digestion of starch into maltose.

Liver:

• Produces bile juice (stored in the gallbladder).
• Bile juice does not contain digestive enzymes but helps in fat emulsification.

Gastric Gland:

• Secretes pepsin (enzyme for protein digestion in the stomach).
• Also produces HCl, which activates pepsinogen into pepsin.

Pancreas:

Secretes pancreatic juice, which contains:

• Trypsin (for protein digestion).
• Lipase (for fat digestion).
• Amylase (for carbohydrate digestion).

Additional Knowledge:

• Trypsin is a proteolytic enzyme that helps in breaking down proteins into peptides.
• Pepsin is active only in the acidic environment of the stomach.
• Bile juice helps in fat digestion by breaking fats into smaller droplets (emulsification), making it easier for lipase to act on them.
