- All organisms use glucose as a primary source of energy. The exception to this is chemoautotrophs which can build all the organic compounds needed for life without using light energy. Chemoautotrophs are often found in extreme environments like volcanoes, salt flats, etc.
- Through a series of enzyme-controlled redox reactions, the bonds are broken (the more stable the covalent bonds are, the more free energy will be released), and the molecule is rearranged into more stable configurations, and energy is released.
- This reaction is a combustion reaction. All combustion reactions are redox reactions in which oxygen is the oxidizing agent, and all are exergonic reactions that release free energy. During the redox reaction, electrons are transferred from glucose to oxygen. Glucose is oxidized to CO2 and oxygen is reduced to water.
