Verified step by step guidance1
Understand the nature of glucose: Glucose is a monosaccharide (simple sugar) that serves as a primary energy source for cells. It contains covalent bonds formed between carbon, hydrogen, and oxygen atoms.
Recall the concept of chemical energy: Chemical energy is stored in the covalent bonds of molecules. When these bonds are broken during metabolic processes, energy is released and used by the cell.
Eliminate incorrect options: Genetic information is stored in DNA and RNA, not glucose. Thermal energy refers to heat, which is not directly stored in glucose. Mechanical energy is related to physical movement, which is also not stored in glucose.
Identify the correct option: The covalent bonds in glucose store chemical energy, which is released during cellular respiration to produce ATP (adenosine triphosphate), the energy currency of the cell.
Conclude: Glucose stores chemical energy in its covalent bonds, making it a vital molecule for energy production in living organisms.
