Transcript of "Cellular respiration within mitochondrium"

  1. 1. GENERAL REACTIONS – overall pathway is exergonicGLYCOLYSIS CITRIC ACID CYCLE & e- TRANSPORT CHAIN Where: Where: cytoplasm mitochondrium General: General Does not use O2 Uses O2 Energy from substrate Most ancient of pathways Overall pathway: Overall pathway:Glucose 2 pyruvate Pyruvate 6CO2 + 6H2O net 2 ATP 36 ATP 2 NADH
  2. 2. Produces large amounts of ATP with O2 acting as e- acceptor. Occurs in the Mtiochondrium PYRUVATE 1. Acetyl CoEnzyme A Coenzyme NAD+ EACH PYRUVATE GENERATES: +H 1 NADH CO2 NADH 1 CO2 (RELEASED) ACETYL CoA CoA
  3. 3. 2. Citric acid cycle/Krebs Cycle CoA CITRATE OXALOACETATE 3 NAD+ ATP 3 NADH ADP + P FAD FADH2 2 CO2 EACH PYRUVATE GENERATES: 3 NADH 1 FADH2 1 ATP 2 CO2
