Question

Statement 1: Instead of glucose, other forms of sugar like fructose or galactose can also be used to obtain energy during respiration.

Statement 2: Fructose and galactose have the same chemical formula of C6H12O6 as that of glucose.

• A. Both statements are true. Statement 2 is the correct explanation of Statement 1.
• B. Both statements are true. But Statement 2 is not the correct explanation of Statement 1.
• C. Statement 1 is true. Statement 2 is false.
• D. Statement 1 is false. Statement 2 is true.

Answer 1

The correct option is D

Statement 1 is false. Statement 2 is true.

Although Fructose and Galactose have the same molecular formula as glucose, their chemical structure is completely different than that of glucose and hence their interaction with oxygen will be different.
