1. What organelle do you need to do cellular respiration?

2. What are the three steps of respiration?

3. What is this lab measuring? ….how do they measure it?

4. What do you use to measure it?

Sketch it to the right and indicate what substances are where.

5. Why does he use KOH (potassium hydroxide)?

6. What are the three different vials/jars and what is the purpose of tube with glass beads?

7. Peas will start to consume _____ and produce _____. But the carbon dioxide will bind with the KOH and precipitate out as a solid. Therefore the volume of gas in the vial decreases as oxygen is consumed. As the volume drops, water moves where?

8. Temperature fluctuations will have a huge influence on this because it effects gas volume, this is why you have a flask of

9. How do you calculate the “rate” of respiration?

10. Why do you think the non-germinating peas respired less?
