  1. Cell Respiration From Glucose  ATP

  2. ATP vs. ADP Adenosine diphosphate Adenosine triphosphate

  3. Anaerobic Respiration • Conversion of C6H12O6 to ATP without the use of oxygen. Alcoholic fermentation (i.e. yeast) Glucose 2 ATP, Alcohol & CO2 Lactic acid fermentation (i.e. mammals) Glucose 2 ATP & lactic acid

  4. Four steps of Aerobic Cell Respiration (uses O2) • Glycolysis • Kreb’s Cycle • Electron Transport Chain • Chemiosmosis

  5. Step #1 Glycolysis (splitting of glucose) • OVERVIEW: Glucose is split into two molecules (3C ea.) • LOCATION: cytoplasm • ATP: 2 • ENERGY CARRIERS:4 NADH • BYPRODUCTS: None

  6. Step #2 Kreb’s Cycle • OVERVIEW: Series of reactions “fueling” the production of energy carriers and ATP. • LOCATION: Mitochondria • ATP: 2 • ENERGY CARRIERS:6 NADH & 2 FADH2 • BYPRODUCTS: CO2

  7. Step #3 Electron Transport Chain • OVERVIEW: • 12 Energy carriers (10 NADH & 2 FADH2 “spark” a series of energy releasing reactions. • Energy released is used to “pump” H+ ions across the membrane (active transport to create a concentration gradient) • LOCATION: Inner membrane of Mitochondria • ATP: 0 • ENERGY CARRIERS:Trigger a chain of reactions • BYPRODUCTS: H2O

  8. Step #4 Chemiosmosis • OVERVIEW: • H+ ions move with the gradient back across the inner membrane. • Movement of H+ ions “fuels” the creation of ATP from ADP • LOCATION: Inner membrane of Mitochondria (@ ATP SYNTHASE) • ATP: Up to 32 • ENERGY CARRIERS:Not involved
