Verified step by step guidance

Understand the structure of a glucose molecule: Glucose (C6H12O6) is a monosaccharide with a six-carbon backbone, hydroxyl groups (-OH), and hydrogen atoms attached to the carbons.

Recognize that energy-storing bonds are typically nonpolar covalent bonds, such as C–H bonds, because they have high potential energy due to the relatively equal sharing of electrons between carbon and hydrogen.

Analyze the types of bonds present in glucose: Glucose contains C–H, C–O, O–H, and other bonds. Among these, C–H bonds are the primary energy-storing bonds because breaking them releases significant energy during metabolic processes like glycolysis and cellular respiration.

Relate this to biochemistry: During cellular respiration, glucose undergoes oxidation, and the energy stored in C–H bonds is released to form ATP, the energy currency of the cell.

Conclude that the correct answer is C–H bonds, as these are the primary energy-storing bonds in glucose molecules, which are utilized during metabolic processes.
