Presentation Transcript

  1. Cellular Respiration Redox reactions

  2. Overall Goal of Cellular Respiration • To extract energy from nutrient molecules and store it in the form that the cell can use for its many energy-requiring activities *glucose transfers energy to ATP • Energy is transferred within living organisms via specialized compounds called energy carriers • ATP is the most commonly used energy carrier donates energy stored in chemical bonds to chemical reactions • NADH and NADPH donate e- via oxidation-reduction reactions

  3. Redox reactions • Cellular respiration is a series of redox reactions where molecules are oxidized and reduced to transfer electrons and as a result, release energy • As a material is oxidized, it loses electrons to another material, which is thereby reduced *LEO the tiger says GER

  4. An example of redox in cellular respiration

  5. Respiration is an example of OXIDATION • Energy is released as H+ and electrons are transferred from glucose to oxygen • Photosynthesis is an example of REDUCTION • Energy is stored as H+ and electrons are transferred from CO2 and water to glucose
