Factors affecting yeast fermentation

Postby princezznichii » Mon May 06, 2019 1:26 am

Hello everyone,
for my Biology internal assessment, I planned to do something related to investigating how increasing the temperature directed to yeast, affects its speed of producing carbon dioxide during yeast fermentation. I have the variables and method all planned out but the thing is, i don't know how i'm going to relate this to biology terms and concepts. I do know that yeast is a simple eukaryotic cell and may functions like one. Besides that, I also know that the cell membrane of yeast may break when uv light is directed on it, but i can't really seem to find and relate other biology concepts.
Does anyone have any idea or is able to help me? I'd very much appreciate it a lot a lot.
Thank you so so much in advance.

Hi,
Sounds like an interesting science project.

Different yeast react differently to different temperatures.
Here's an experiment that explains the background for that idea:

This experiment explains what biologically can happen to yeast at different temperatures:

Hope this helps,
