It is the most abundant monosaccharide in nature.
Correct answer: D. Glucose
- A. Ribose
- B. Maltose
- C. Cellulose
- D. Glucose
Explanation
The correct answer is glucose. Glucose is the most abundant monosaccharide found in nature. It is a crucial energy source for living organisms and is a fundamental building block for many carbohydrates. In contrast, ribose is a component of RNA and is not as abundant as glucose. Maltose is a disaccharide consisting of two glucose molecules, and cellulose is a polysaccharide made from glucose units, primarily found in plant cell walls. Neither maltose nor cellulose is a monosaccharide.

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.
