Presentation Transcript

  1. Cellular respiration is anaerobic process • Cellular respiration is an • aerobic process • 1 C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP • glucose total energy • 􀁡oxygen-dependent (mice) • 􀁡carbon dioxide production (seeds

  2. Cellular Respiration • 􀁡Aerobic respiration • 􀁠Mice exercise • 􀁠Seed exercise • 􀁠Mitochondrion model • 􀁡Fermentation (anaerobic)Yeast exercise

  3. Measuring oxygen consumption ofmice exercise • Measuring oxygen consumption of • mice exercise • 1 C6H12O6 + 6 O2 6 CO2 + 6 H2O + 38 ATP • glucose total energy • 􀁡KOH pellets used to remove CO2 • 􀁡oxygen-consumption is measured • 􀁡Mass specific VO2 is determined • 􀁡Each group • 1 setup apparatus, run 3 trials, clean up • 2 determine average • 3 calculate class average

  4. CO2 productionby germinating seeds exercise • C6H12O6 + 6 O2 gives 6 CO2 + 6 H2O + 38 ATP • glucose total energy • Flask #􀁡1 germinating • 􀁡2 germinating-boil • Results after hr • 􀁡CO2 production, phenol red = yellow • 􀁡no CO2, phenol red = red

  5. Fermentation • 1 glucose with yeast gives 2 ethanol + 2 CO2 + energy • C6H12O6 C2H5OH 2 ATP • 􀁡Oxygen independent • 􀁡Alcoholic fermentation (yeast exercise

  6. Alcoholic fermentation ex. • Alcoholic fermentation ex. • 1 glucose 2 ethanol + 2 CO2 + 2 ATP • C6H12O6 C2H5OH energy • 20ml beaker solution = glucose + 0.5g yeast • 􀁡1 10% glucose • 􀁡2 1% glucose • 􀁡3 0% glucose • Expected Results • 􀁡most CO2 • 􀁡intermediate • 􀁡 no CO2

  7. Mitochondrion model • Mitochondrion model • 1 C6H12O6 + 6 O2 6 CO2 + 6 H2O + 38 ATP • glucose total energy • 􀁡Locate • 􀁠outer membrane • 􀁠inner membrane (Cristae) • 􀁠intermembrane space • 􀁠matrix • 􀁡Function: aerobic respiration, making ATP
