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
Cellular Respiration • Aerobic respiration • Mice exercise • Seed exercise • Mitochondrion model • Fermentation (anaerobic)Yeast exercise
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
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
Fermentation • 1 glucose with yeast gives 2 ethanol + 2 CO2 + energy • C6H12O6 C2H5OH 2 ATP • Oxygen independent • Alcoholic fermentation (yeast exercise
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
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
