Cellular respiration is an energy releasing enzymatically controlled catabolic process which evolves a stepwise oxidative breakdown of organic substances inside living cells. Describe the steps involved in cellular respiration when oxygen is and is not available. In your answer, state the inputs and outputs of yeast cell respiration with and without oxygen.
a.
In the yeast respiration experiment, we saw that yeast were able to use sucrose (table sugar) for respiration, but not sucralose (the active ingredient in Splenda).
b. b. Explain what these results indicate about how the specific structure of an enzyme affects its function. In your answer, make sure to include the term “active site.”
c. c. Explain how you think the results may have differed if the fermentation tubes had been placed in a refrigerator (~4 degrees Celsius) over the duration of the experiment, instead of an incubator set to 40 degrees Celsius, and why.
In the photosynthesis experiment with spinach, we filled the leaf discs with sodium bicarbonate and placed the leaf discs under a light source.
d. d. Do you think that this experiment would have worked equally well if we had just used water? Why or why not?
e. e. Do you think that this experiment would have worked equally well if we had not used a light source? Why or why not?
