Glucose contains chemical bonds with high-energy electrons. When the bonds are broken during cellular respiration, this energy is released and used to run the ATP-making machinery in the mitochondria. Which of the following bonds found in glucose contains the least energy (has the lowest energy electrons)?

Linear glucose carries a [tex]C_6H_1_2O_6[/tex] molecular model. The links between all the atoms bu tone are single bonds, while at the end one Carbon-Hydrogen bond is a double bond. The linear glucose molecule is structured from four different forms of bonds: C-C, C-H, C-O and O-H. The carbon atoms in glucose originate from the molecules of ambient carbon dioxide which are taken in for photosynthesis by plants.

The Carbon-Oxygen connection has an electronegativity of 1 which makes it moderately covalent. Glucose is a form of molecule of sugar which plants make throughout the photosynthesis mechanism. Green plants and other autotrophic species comprise of the capacity to absorb the energy of the sun and using it to fuel this process, preserving the energy in the glucose molecule inside the bonds.
