anaerobic/aerobic yeast growth

[alnj90]

I am considering the project "Yeast Metabolism with and without aeration". I understand how to perform the experiment, but I am having trouble discerning WHY this is important. What are the 'real world' applications? Thank you. ?

Hi,

So you are trying to understand the difference and importance of aerobic vs. anaerobic metabolism. I looked up your referenced project writeup:
https://www.sciencebuddies.org/science- ... p009.shtml

And looked at the bibliography, so I can understand your frustration, as the first two of the three reference links appear broken. The third link does work and seems to me informative:

http://biology.clc.uc.edu/courses/bio104/cellresp.htm

You might also want to look into these related projects:

https://www.sciencebuddies.org/science- ... p040.shtml

https://www.sciencebuddies.org/science- ... p011.shtml

As far as the big picture goes, anaerobic yeast metabolism is hugely important - think fermentation of wine, beer, making bread, making liquor, etc. Yeast grows better aerobically as it can get more energy out of the sugars it is eating.

Hope this helps/ This can be a really interesting project!

Best regards

Hi alnj90 - I am sorry that you ran into outdated links in the bibliography section of the project you are considering. Barrett has given you some good information regarding the topic. I also have some new links to share with you that will replace the ones in the project that no longer work. These two links will be added into the bibliography of that project, so you may want to check these for additional background information:
