Transcript

  • 1.  
  • 2. Why/Where do metabolic functions occur?
    • We have metabolic functions within our bodies and cells because they produce energy and fundamental components essential to human life.
    • Metabolic Functions occur in the cytosol and the mitochondria.
  • 3. Anaerobic Respiration
    • Anaerobic: Without oxygen; with lactic acid.
    • Mainly used by bacteria that live in places devoid of oxygen.
    • The three main steps of cell respiration are still used, just without oxygen
    • Final electron acceptor still functions but replaces oxygen with sulfate (SO4) nitrate (NO3) and sulfur (S)
  • 4. Aerobic Respiration
    • Aerobic: With oxygen.
    • Breakdown of glucose to carbon dioxide and water in the presence of oxygen.
    • Most productive pathway of cellular respiration
    • Produces 34 ATP molecules
  • 5. Adenosine Triphosphate
    • More commonly known as ATP.
    • ATP is synthesized and used in:
      • Glycolysis
      • Electron Transport Chain
      • The Krebs Cycle (The Citric Acid Cycle)
      • All of these functions make up both Aerobic and Anaerobic respiration within a cell.
  • 6. Glycolysis
    • Glycolysis occurs in the cytosol, the liquid portion of cytoplasm.
    • Products: 2 ATP, 2 NADH, 2 Pyruvate Molecules
    • Glycolysis is the process that converts glucose to pyruvate.

  • 7. The Krebs Cycle
    • Aerobic respiration.
    • In eukaryotic cells, this occurs in the mitochondrion.
    • Products: 1 ATP, 3 NADH, 2 CO2, 1 QH2

  • 9. Electron Transport Chain
    • Process: Special carrier molecules bring the high-energy electrons to a series of enzymes that convert remaining energy to more ATP molecules
    • Products: Heat and H 2 O
    • Creation of hydrogen ion gradient
