Cellular respiration (chapter 9): introduction I. How cells harvest chemical energy (an introduction) II. Redox reactions (oxidation-reduction reactions) A. In cellular respiration, a nutrient (like glucose) is oxidized in a multi-step process  involving oxidation-reduction reactions. As a result, the cell regenerates ATP. (See  overall reaction) B. What are oxidation-reduction reactions? And, how are they used in the process of  cellular respiration? 1. Definition: oxidation-reduction reactions are reactions in which 1 or more  electrons are transferred from one molecule to another. Sometimes, these  reactions don't involve the complete transfer of electrons, but involve the change  in degree of electron sharing within covalent bonds between atoms. Electrons are  moved to more stable positions.
