Redox reaction in photosynthesis and cellular respiration
Redox cycling[ edit ] A wide variety of aromatic compounds are enzymatically reduced to form anfertigung einer dissertation radicals that contain one more electron than their parent compounds. In this particular part of the electron transport chain some molecules also accept and release protons, pumping them into the intermembrane space creating a proton gradient.
Balancing redox reactions[ edit ] Describing the overall electrochemical reaction for a redox process requires a balancing of the component half-reactions for oxidation and reduction. Therefore, glucose is oxidized, while oxygen is reduced in cellular respiration. In respiration, electrons are transferred from glucose molecules to oxygen.
Glycolysis and the Krebs Cycle Energy is created in cellular respiration through the oxidization of glucose and its derivatives. Taylor "The Cell, Respiration, and Photosynthesis.
