Question:
Given below are two statements. Statement I - Lactose on hydrolysis converts in to glucose and galactose. Statement II - Galactose also plays same role as glucose in respiration. In the light of above statements, select the correct option given below:
Given below are two statements. Statement I - Lactose on hydrolysis converts in to glucose and galactose. Statement II - Galactose also plays same role as glucose in respiration. In the light of above statements, select the correct option given below:
Show Hint
Lactose gives glucose and galactose, and galactose can enter the respiratory pathway after conversion.
Updated On: Nov 13, 2026
- Both statement I and statement II are correct.
- Both statement I and statement II are incorrect.
- Statement I is correct but statement II is incorrect.
- Statement I is incorrect but statement II is correct.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Lactose is the milk sugar, a disaccharide.
Step 2: Statement I
On hydrolysis lactose breaks into one glucose and one galactose molecule. Statement I is correct.
Step 3: Statement II
Galactose is converted into glucose derivatives in the liver and enters glycolysis, so it can serve as a respiratory substrate like glucose. Statement II is correct.
Step 4: Compare the options
Both statements are correct.
Final Answer:
Both statements are correct. \[ \boxed{\text{(A) }\text{Both statement I and statement II are correct.}} \]
