Question

Given below are two statements:
Statement I - During digestion, the disaccharides are broken down in the large intestine.
Statement II - Disaccharides are insoluble in water.
In the light of the above statements, choose the most appropriate answer from the options given below:

• A. Both statement I and statement II are correct.
• B. Both statement I and statement II are incorrect
• C. Statement I is correct but statement II is incorrect.
• D. Statement I is incorrect but statement II is correct.

Hint:

Decide where disaccharides are digested and whether they dissolve in water.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
We must check each statement about disaccharides separately.

Step 2: Statement I
Disaccharides such as maltose, sucrose and lactose are broken into monosaccharides in the small intestine by maltase, sucrase and lactase. The large intestine makes no such enzymes, so Statement I is incorrect.

Step 3: Statement II
Disaccharides have many hydroxyl groups that form hydrogen bonds with water, so they dissolve easily (like table sugar). Statement II is incorrect.

Final Answer:
Both statements are incorrect. \[ \boxed{\text{(B) }\text{Both statement I and statement II are incorrect}} \]
