Question

question 5 of 10
which of the following secretions from the stomach aids in the absorption of vitamin b12?
hydrochloric acid
gastric lipase
pepsin
intrinsic factor

Explanation:

• Hydrochloric acid helps in protein digestion and activating pepsin, not directly in vitamin B12 absorption.
• Gastric lipase is involved in lipid digestion.
• Pepsin is for protein digestion.
• Intrinsic factor binds to vitamin B12, protecting it from digestion and enabling its absorption in the ileum.

Answer:

Intrinsic factor
