Question

Which of the following pair of organs do NOT produce digestive enzymes?

• A. Large intestine and Liver
• B. Liver and pancreas
• C. Duodenum and jejunum
• D. Salivary glands and stomach

Hint:

Liver produces bile, not enzymes, and the large intestine mainly absorbs water without secreting digestive enzymes.

Answer 1

The Correct Option is A

Concept:
Digestive enzymes are produced by various organs to break down food:
• Salivary glands → Salivary amylase
• Stomach → Pepsin, gastric lipase
• Pancreas → Trypsin, lipase, amylase
• Small intestine → Intestinal enzymes However, some organs aid digestion without producing enzymes.

Step 1: Identify organs that do NOT produce enzymes.
• Liver → Produces bile (no enzymes)
• Large intestine → No digestive enzyme secretion

Step 2: Analyze the given options.
• (A) Large intestine and Liver → Both do NOT produce enzymes \checkmark
• (B) Liver and pancreas → Pancreas produces enzymes $\times$
• (C) Duodenum and jejunum → Both produce intestinal enzymes $\times$
• (D) Salivary glands and stomach → Both produce enzymes $\times$

Step 3: Conclusion. Thus, the organs that do not produce digestive enzymes are: \[ \text{Large intestine and Liver} \]
