Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Many single-celled organisms rely primarily on monosaccharides and disaccharides as their source of energy. Which class of biomolecules provides the energy for these cells?

A	Lipids
B	Carbohydrates
C	Nucleic Acids
D	Proteins

Explanation:

Detailed explanation-1: -Carbohydrates, lipids and proteins are usually used to provide energy in an organism.

Detailed explanation-2: -Glucose, a 6-carbon sugar, is a simple carbohydrate or “mono-saccharide.” Sugar is a source of quick energy for the body because it is easily metabolized (broken down).

Detailed explanation-3: -The most important monosaccharide is glucose, a carbohydrate with the molecular formula C6H12O6. Glucose is the basic form of fuel in living things. In multicellular organisms, it is soluble and is transported by body fluids to all cells, where it is metabolized to release its energy.

Detailed explanation-4: -In most living species, glucose is an important source of energy. During cellular respiration, energy is released from glucose, and that energy is used to help make adenosine triphosphate (ATP).
