Glucose is:
Correct answer: A. Aldose hexose sugar
- A. Aldose hexose sugar
- B. Furanose pentose sugar
- C. Ketose hexose sugar
- D. Pyranose Pentose sugar
Explanation
Glucose is classified as an aldose hexose sugar because it contains an aldehyde group (making it an aldose) and has six carbon atoms (making it a hexose). The other options are incorrect because:Furanose pentose sugar: Glucose is not a furanose pentose as it does not form a five-membered ring nor does it have five carbon atoms.Ketose hexose sugar: Glucose contains an aldehyde group, not a ketone, which is characteristic of ketoses like fructose.Pyranose Pentose sugar: While glucose can form a pyranose ring, it is not a pentose as it has six carbon atoms.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
