Presentation Transcript

  1. Respiration • 1. Anaerobic • Cytoplasm • Glycolysis • Sucrose 4 Pyruvates • 4ATP • 4 NADH

  2. Respiration • 2. Aerobic • Mitochondria • Krebs Cycle (Citric Acid or TCA Cycle) • 4 Pyr ---> 12 CO2 • 4 ATP • 16 NADH • 4 FADH

  3. Respiration • 3. Total (1+2) • Sucrose ---> 12 CO2 • 8 ATP • 20 NADH = 60 ATP • 4 FADH = 8 ATP • ________________ • 76 ATP for every Sucrose

  4. Glycolysis • Sucrose (12C) Glucose (6C) + Fructose (6C) Invertase - ATP • Glucose G-6-P - ATP • Fructose F-6-P • G-6-P F-6-P (2 x 6C) • -2 ATP (Energy Requirement)

  5. Glycolysis -2 ATP • 2 F-6-P 2 F-1,6 bisP • 2 F1,6bisP 4 PGAL • + 4 NADH • + 4 Pi • 4 PGAL 4 1,3-diPGA • + 4 ATP • 4 1,3 diPGA 4 PGA • Net = 4 NADH

  6. Glycolysis • 4 PGA 4 PEP C4 & CAM + 4 ATP - CO2 • 4 PEP 4 PYR Ethanol (2C) -O2 + O2 Mitochondria 4 x (3 C) = 12 C Net = + 4 NADH + 4 ATP

  7. Glycolysis Sucrose 12 C 2 x 6 C 2 x 6 C 4 x 3 C Pyruvate

  8. Krebs Cycle • 4 PYR 12 CO2 • + 4 NADH • + 1 FADH • + 4 ATP

  9. Energy Recovery • GLYCOLYSISKREBSTOTAL • ATP 4 4 8 • NADH 4 16 20 • FADH 0 4 4

  10. Electron Transport Chain

  11. Final Products • Sucrose • 12 CO2 TCA from Sucrose • - 6 O2 Electron Transport • - 24 H+ NADH +FADH • 12 H2O Electron Transport • 68 ATP Electron Transport • 8 ATP TCA + Glycolysis • 76 ATP • 8 Cal / ATP • 608 Cal / mole of Sucrose
