Which of the foIIowing sugar is mainly present in human blood?
Correct answer: A. Glucose
- A. Glucose
- B. Sucrose
- C. Fructose
- D. Mannose
Explanation
Glucose: The correct option is glucose. Glucose is the main sugar present in human blood and serves as a primary source of energy for the cells in the body. After consuming carbohydrates from food, the digestive system breaks down complex carbohydrates into glucose, which is then absorbed into the bloodstream. Glucose is transported through the bloodstream and taken up by various tissues and organs to provide energy for cellular processes. Sucrose: Sucrose is a disaccharide composed of one glucose molecule and one fructose molecule linked together. It is commonly known as table sugar and is found in various sweet foods. However, sucrose is not the primary sugar present in human blood.Fructose: Fructose is a monosaccharide, and while it is found in certain foods like fruits and honey, it is not the primary sugar present in human blood. Mannose: Mannose is another monosaccharide, and it is essential for various cellular processes. However, it is not the primary sugar present in human blood.In summary, the correct option is a) Glucose. Glucose is the main sugar present in human blood and serves as the primary energy source for cells and tissues throughout the body.

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.
