Question

Vitamin \(\text{B}_{12}\) is synthesised in (A) and intrinsic factor present in (B) helps in absorption of vit \(\text{B}_{12}\) from food.

• (A) - Stomach ; (B) - Bile juice
• (A) - Liver; (B) – Gastric juice
• (A) - Liver ; (B) Succus entericus
• (A) - Duodenum ; (B) - Pancreatic juice

Hint:

Intrinsic factor is released by the stomach and is part of gastric juice.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Intrinsic factor is released by the oxyntic cells of the stomach along with HCl, so it is a component of gastric juice.

Step 2: Role in absorption
It binds vitamin \(\text{B}_{12}\) so that the ileum can absorb it. Bile, succus entericus and pancreatic juice do not contain intrinsic factor.

Step 3: Choose the pairing
Only one option pairs intrinsic factor with gastric juice, and it names the liver, the organ that stores the body's vitamin \(\text{B}_{12}\), for blank (A).

Final Answer:
The pairing is liver for (A) and gastric juice for (B). \[ \boxed{\text{(B) }\text{(A) - Liver; (B) - Gastric juice}} \]
