Gastric glands produce the enzyme ___________ during digestion, which digests proteins.

Correct option is A

The correct answer is (A) Pepsin.

Explanation:
The gastric glands in the stomach produce the enzyme pepsin, which helps in digesting proteins.

Other options explanations:

• Trypsin: Produced by the pancreas, not the gastric glands.
• Helicase: Involved in DNA replication, not digestion.
• Lactase: Breaks down lactose in the small intestine, not proteins.

Information booster:

• Pepsin: Secreted in an inactive form called pepsinogen, activated in the acidic environment of the stomach.
• Enzyme function: Breaks down proteins into smaller peptides.
