Question
The diagram is a model of the structure of glucose.
The structural formula of glucose, C6H1206, shows a ring of 5 carbon atoms and 1 oxygen atom. 4 carbons in the ring are each bonded to an -H and an -OH group in addition to 2 neighboring atoms in the ring. The fifth carbon is bonded to a CH2OH group.
What structural feature does glucose share with larger carbohydrates?
A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom
B. the presence of double covalent bonds between carbon atoms
C. strong bonds between carbon atoms that cannot be broken
D. ionic bonds between carbon atoms and oxygen atoms

The correct answer is:
**A. a ratio of 1 carbon atom to 2 hydrogen atoms to 1 oxygen atom.**
Glucose and larger carbohydrates (polysaccharides) share this characteristic ratio, which is a defining feature of carbohydrates in general.
