Question

The most important monosaccharides for energy storage is _____ which has _____ energy storing C-H bonds
Options
A Galactose, 6
B Glucose, 6
C Sucrose, 7
D Glucose 7
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Glucose is the most important monosaccharide for energy storage in living organisms. It has the molecular formula C6H12O6. To determine the number of C-H bonds, we look at its structure. Counting the bonds in the linear form or ring form is tricky. A typical glucose molecule has 7 C-H bonds (if you count all hydrogens attached directly to carbons). Option D says 'Glucose 7', which is correct. Option B says 'Glucose, 6' which is wrong.

Hint

Which six-carbon sugar is the primary energy currency in cells, and how many C-H bonds does its ring structure contain?
