Question

Choose the correct answer among the following:

Gastric juice contains

• A. pepsin, lipase and rennin
• B. trypsin ,lipase and rennin
• C. trypsin, pepsin and lipase
• D. trypsin, pepsin and renin

Answer 1

The correct option is A

pepsin, lipase and rennin

The correct option is A

Explanation of correct option:

1. Gastric juices secreted by the stomach have a pH of 1.8 due to HCL secreted into it.
2. Gastric chief cells secretes inactive zymogen like pepsinogen, lipase, and renin.
3. Pepsinogen gets activated in acidic pH and convert into active pepsin.
4. Pepsin is a protein-digesting enzyme.
5. Pepsin converts proteins into proteoses and peptones.
6. Lipase help in fat digestion, and little fat digestion does take place in the stomach.
7. Rennin is an enzyme found in the gastric juice of infants that helps in milk protein digestion.
8. Pancreatic juice-secreted trypsinogen is an inactive enzyme.
9. Trypsinogen gets converted into active trypsin by the enzyme enterokinase.
10. Trypsin is a proteolytic enzyme.

Final answer: Pepsin, lipase, and renin is secreted by gastric juice.
