  1. LAB 5Cellular Respiration http://www.phschool.com/science/biology_place/labbench/lab5/process.html

  2. 6 12 6 2 2 2 C H O + 6O → 6 H O + 6 CO • KOH turns CO gas into a solid • So changes in volume will be due to ? 2 http://www.phschool.com/science/biology_place/labbench/lab5/respwork.html

  3. CONTROL • If you want to control variables the contents of the vials must start the SAME • How can you measure the volume of an irregularly shaped object, like peas?

  4. Make another set 1, 2, 3 will go in room temp; 4, 5, 6 will go in 10° water http://www.phschool.com/science/biology_place/labbench/lab5/assemble.html

  5. Place respirometers in water bath with tips of pipettes • resting on a masking tape sling above the water level. • Wait 7 MINUTES for temperature to equilibrate. • Add a drop of RED FOOD COLOR into the tip of each pipette http://www.phschool.com/science/biology_place/labbench/lab5/measure.html

  6. Lower the pipettes into water • Quickly align the tubes so you can read the numbers • Wait 3 MINUTES • Record level of water in each pipette and start timer • Take readings from each respirometer at 5 minute intervals for 20 minutes • REPEAT with 2nd set of respirometers in ice water http://www.phschool.com/science/biology_place/labbench/lab5/measure.html

  8. HOW DOES TEMPERATURE AFFECT THE RESPIRATION RATE IN AN ORGANISM? Warm blooded(Endothermic) Cold blooded(Ectothermic) http://www.lbreptileexperience.com/adventures.html http://www.uselessgraphics.com/rats.htm
