Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which biomolecule is a source of fast, quick energy for cells?
A
carbohydrates
B
lipids
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -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-2: -Simple carbohydrates: Various forms of sugar, such as fructose (fruit sugar) and sucrose (table sugar), are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy.

Detailed explanation-3: -Carbohydrates are the body’s main source of quick energy because very little energy is required to break them down. There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides.

Detailed explanation-4: -Adenosine triphosphate (ATP) is a high-energy compound that provides energy for a wide range of cellular processes. ATP is produced through the breakdown of glucose via two pathways.

Detailed explanation-5: -The energy released during a catabolic reaction is conserved in the form of a high-energy molecule (ATP). The biomolecules which are undergoing catabolic reactions are carbohydrates, proteins, and lipids.
