Presentation Transcript

  1. Cellular Respiration Laboratory Investigation

  2. 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

  3. 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

  4. Measuring Respiration in Living Organisms

  5. Procedure Preparations • 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
