What was this experiment about? What did we learn from it?

  1. This tray is teaching us about respiration. Also, Alot like us Yeast breathes in Oxygen and out Carbon Dioxide. If it, didnt the BTB would not have became pale yellow or a pale green. So, In Conclusion most organsims have respiration.

  3. This tray teaches us cellular repiration. This is the process of using oxygen, to break down your sugars. All cellular respiration takes place in your mitochondria.

  5. The tray is teaching us that yeast need to breathe just like us. When you give them sugar, they break it down and use oxygen to produce energy in the cell's mitochondria, so that the yeast can have energy.

    P.S. My group's tray had the best results in group 6 and the oval cup was really yellow :)

  6. The tray is teaching us about cellular respiration. Living yeast takes in oxygen to break down sugars, therefore producing energy. The mitochondria in the yeast that does this then exhales carbon dioxide, which goes through the yellow tube and into the BTB, which turns a yellow color.
