Aerobic and Anaerobic Respiration in Yeast Cells

The...Yeastiest way to produce energy? Dave Phillipich February 28, 2001 Dr. Krufka MWF 1:30-3:30 Lab Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs, yet only the latter requires oxygen. Got that? Didn’t think so. Cellular respiration is a very complex process …showed first 75 words of 720 total…

…showed last 75 words of 720 total…respiration rates. What does this mean for us? Well, it means we produce energy at a faster rate when we are hot, compared to when we are cold. For another experiment, I think it would be interesting to see how long it takes for a yeast solution in a cold environment to release the same amount of CO2 as a yeast solution in a hot environment. The same procedure would be followed, stabilizing the results.
