When the glucose level in the blood comes down, glucose is synthesized from:
Correct answer: B. Glycogen
- A. Fats
- B. Glycogen
- C. Amino acids
- D. DNA
Explanation
When blood glucose levels decrease, the body can break down glycogen stored in the liver and muscles into glucose through a process called glycogenolysis. This glucose is then released into the bloodstream to maintain a stable blood sugar level. Fats are broken down into fatty acids and glycerol, while amino acids can be converted into glucose through gluconeogenesis. DNA does not play a role in glucose synthesis in 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.
