  • Cellular Respiration By Courtney Gates
  • Slide 3
  • Definition Cellular respiration is the process by which mitochondria break down food molecules to produce ATP Equation: C H O +6O 6CO +6H O
  • Slide 4
  • Stages Three stages of cellular respiration: 1. Glycolysis 2. Krebs Cycle 3. Electron Transport Chain
  • Slide 5
  • Glycolysis Glycolysis is a series of chemical reactions in the cytoplasm of a cell that break down glucose into two molecules of pyruvic acid and a three-carbon compound Two ATP are used Two ATP are produced and NADH carries electrons
  • Slide 6
  • Oxidation of Pyruvate Before the Krebs cycle pyruvic acid undergoes a series of chemical reactions It gives off CO It combines with coenzyme A to form acetyl-CoA
  • Slide 7
  • Krebs Cycle Is also known as the Citric Acid Cycle Is a series of chemical reactions and for every turn of the cycle two ATPs, two CO molecules, and NADH and FADH are produced
  • Slide 8
  • Electron Transport Chain NADH and FADH give up electrons that pass through a series of chemical reactions Oxygen is the final electron acceptor which ends up producing water Produces 32 ATP
  • Slide 9
  • ATP Produced 4 ATP molecules are produced from the Krebs Cycle (2 from each pyruvate) 32 ATP molecules are produced from the Electron Transport Chain
