  3. Cellular Respiration ANAEROBIC A. Glycolysis: AEROBIC B. Pyruvate Oxidation & Citric Acid Cycle (Kreb Cycle) C. Oxidative Phosphorylation

  4. Cellular RespirationStage 1:Glycolysis 2007-2008

  5. CH2OH O Glucose 1 ATP hexokinase ADP CH2 O P O Glucose 6-phosphate 2 phosphoglucose isomerase CH2 P O CH2OH O Fructose 6-phosphate 3 ATP phosphofructokinase P O CH2 CH2 O P O ADP Fructose 1,6-bisphosphate aldolase 4,5 H O CH2 P isomerase C O C O Dihydroxyacetone phosphate Glyceraldehyde 3 -phosphate (G3P) CHOH CH2OH CH2 O P NAD+ Pi NAD+ Pi 6 glyceraldehyde 3-phosphate dehydrogenase NADH NADH P O O CHOH 1,3-Bisphosphoglycerate (BPG) 1,3-Bisphosphoglycerate (BPG) CH2 O P 1st Glucose Priming

  8. Glycolysis summary ENERGY INVESTMENT -2 ATP G3P C-C-C-P ENERGY PAYOFF 4 ATP like $$in the bank NET YIELD

  9. Energy Transformations in Glycolysis

  10. Glycolysis Breaking down glucose glucose      pyruvate 6C 3C 2x In thecytosol?Why doesthat makeevolutionarysense? That’s not enoughATP for me!

  11. Evolutionary perspective Prokaryotes Anaerobic atmosphere Prokaryotes that evolved glycolysis are ancestors of all modern life ALL cells still utilize glycolysis You meanwe’re related?Do I have to invitethem over for the holidays?
