  • Cellular Respiration8.3

  • I. Cellular RespirationCellular Respiration- The process that breaks down food molecules (glucose) into ATP1. Takes place mostly in the mitochondria

  • I. Cellular RespirationB. Aerobic- Requires oxygen

    C. Anaerobic- Does NOT require oxygen

  • I. Cellular RespirationD. 3 Stages1. Glycolysis2. Citric Acid Cycle3. Electron Transport Chaina) Oxygen is the final electron acceptor required to start ETC

  • I. Cellular RespirationSee overhead for charts on glycolysis, acetyl coA formation, citric acid cycle and electron transport chain

  • I. Cellular RespirationSee overhead for charts on glycolysis, acetyl coA formation, citric acid cycle and electron transport chain

  • II. FermentationOccurs during times of intense exercise until oxygen is available again

  • II. FermentationB. Lactic Acid Fermentation1. Glucose is converted pyruvic acid2. Pyruvic acid is converted to lactic acida. Causes muscle fatigue3. 2 ATP are produced

  • II. Fermentation4. Anaerobic5. Takes place in mitochondria

  • II. FermentationC. Alcoholic Fermentation1. Glucose is converted to pyruvic acid2. The pyruvic acid is broken down into CO2 and alcohol3. 2 ATP are created

  • II. Fermentation4. Anaerobic5. Takes place in mitochondria of yeast

  • II. Fermentation4. Alcoholic fermentation is used in:a. ethanol productionb. bread bakingc. beer & wine5. Yeast do the fermentation

  • RECAPWhat is the goal of cellular respiration?What are the 3 stages of cellular respiration?What are the beginning reactants and ending products of each stage?

  • RECAPWhy is oxygen important in respiration?What is the difference between lactic acid fermentation and alcoholic fermentation?
