Laboratory Investigation

measuring respiration in living organisms
Measuring respiration in living organisms
  • What types of organisms carry out aerobic cellular respiration?
  • How do we know?
  • How can we measure the rate of respiration?

C6H12O6 + 6O2 6CO2 + 6H2O

measuring respiration in living organisms1
Measuring Respiration in Living Organisms
  • Hypothesis 1 - Organismal
    • Cricket vs. Germinating Pea vs. Dry Pea
      • Rank the organisms from high to low rate of respiration, and explain.
  • Hypothesis 2 - Temperature
    • Low vs. Room, explain your reasoning
      • Cold greater than warm
      • Warm greater than cold
      • Equal rates
      • No respiration for either
preparations
ProcedurePreparations
  • Place probe in chamber (don’t twist!)
  • Wait 2min before collecting data
  • Collect data for two minutes
  • Hit stop
  • Save the file as
    • [grp#][org][temp]
    • Email to me
  • Set up low temp first
    • Put orgs in chamber
    • Put chamber in plastic beaker and fill around with ice
  • Run room temp while orgs are cooling down
  • Run low temp after 10 minutes
