List the energy pathways of the body and how much ATP each one produces per 1 substrate. HINT: There should be four (two anaerobic and two aerobic).
a. 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. 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,…
