  • Cellular Respiration

    The process where eukaryotic cells generate energy for their needs by breaking down glucose into carbon dioxide, which releases ATP, which is then used by the cell for its energy needs.
  • SUMMARY OF CELLULAR RESPIRATION PART 1
    • Glycolysis breaks glucose (C6H12O6) into TWO molecules of pyruvate (C3H3O3) and produces NADH and ATP
    • Pyruvate oxidation and the Citric Acid Cycle
    • Pyruvate is oxidized into acetyl CoA, producing NADH
    • Acetyl CoA enters the Citric Acid Cycle (produces FADH2 as well as Oxidative phosphorylation)
  • SUMMARY OF CELLULAR RESPIRATION PART 2
    • Composed of 2 steps: electron transport and chemiosmosis
    • Electron Transport: NADH and FADH2 (Formed from 2 steps above) here, protons are pumped into the mitochondrial inter membrane space
    • Chemiosmosis: proton gradient powers ATP synthase, generating ATP. Here, the pumped protons return to the inner mitochondrion. Upon entry, they power the ATP synthase
    • Bulk transport - uses vesicle
