Presentation Transcript

  1. Cell Respiration Chapter 9

  2. 2 Catabolic Pathways • Cell Respiration • Called Aerobic Respiration • Requires Oxygen • Fermentation • Called Anaerobic Respiration • Oxygen NOT needed

  3. Cellular Respiration

  4. Cellular Respiration

  5. Glycolysis • Splitting of glucose • Cytosol (cytoplasm) • 6-Carbon molecule  2 (3-Carbon molecules) • 2 Phases • Energy Investment (Consumes 2 ATP) • Energy Payoff (Produces 4 ATP)

  6. Questions • What are the 2 catabolic pathways? • How do they differ? • What are the 4 parts of cellular respiration? • Which of the parts produce ATP? • Which of the parts produce NADH? • Which part(s) of cellular respiration require oxygen?

  7. Pyruvate Oxidation • Pyruvate  Acetyl CoA • 3-Carbon  2 Carbon • Needs to get into the mitochondrion • Transport protein • Produces • NADH or FADH2 • CO2

  8. Citric Acid Cycle • Called Kreb’s Cycle OR TricarboxylicAcic Cycle (TCA) • Mitochondria • Produces • CO2 • NADH • FADH2 • ATP (Actually GTP  ATP)

  9. Questions • What are the 4 Parts of Cellular Respiration? • What is Glycolysis? • What is produced in Glycolysis? • Where does Glycolysis occur in a eukaryotic cell? • Where does it occur in a prokaryotic cell?

  10. Oxidative Phosphorylation • 2 Parts: • Electron Transport Chain • Chemiosmosis • Electron Transport Chain • Embedded in inner mitochondrial membrane • Pumps Protons out of the Inner mitochondrial space • Establishes electrochemical gradient • Chemiosmosis • ATP Synthase makes ATP

  11. Questions • What are the 4 Parts of Cellular Respiration? • What is the purpose of Pyruvate Oxidation? • What is produced in Pyruvate Oxidation? • For each glucose, how many pyruvate oxidations occur? • Where does the TCA cycle occur in a eukaryotic cell? • Where does it occur in a prokaryotic cell?

  12. Questions (Page 2) • For each glucose, how many turns of the TCA cycle occur? • Each turn of the TCA cycle produces how much: • CO2? • ATP? • NADH? • FADH2? • What are the 2 alternate names for the TCA cycle?

  13. Fermentation • 2 Forms • Lactic Acid fermentation • Alcoholic fermentation • Glycolysis + 1 extra step (Recycles NAD+) • Does NOT use oxygen

  14. Fermentation • Lactic Acid Fermentation • 3-Carbon  3-Carbon • 3-carbon = Lactate or Lactic acid • Muscles • Alcoholic Fermentation • 3-Carbon  2-Carbon • 2-Carbon = Ethanol • CO2 • Beer or wine
