Science Buddies: "Ask an Expert"

Is there a way to assess mitochondrial function by measuring how much CO2 is exhaled? If so, how would this be done?

Hello,
Is this related to a hands-on science project in grades K-12? If so, please describe the project in more detail, including the hypothesis and the experiments planned. Otherwise, there are other sites on the internet where your question would be more appropriate.

Thank you,

Yes, my question is related to a science fair project. I am hoping to determine whether mitochondria function at differing rates at higher altitude and at varying temperature. I do realize that the human body stays at relatively the same temperature no mater what the exercise conditions- but other perimeters are altered, such as dehydration rate, etc... I have yet to completely design my experiment but was wondering if it was even possible to simply detect mitochondrial output.

Hi Hudsonsciencefair!

What a cool topic! Luckily there is a way to assess mitochondrial function by monitoring either carbon dioxide or oxygen. I recently did a lab like this in my bio class and we utilized a tool called a respirometer and monitored the respiration rate by the amount of oxygen used. Our teacher gave us a virtual lab and recommended some videos to watch prior to class, which I’ll attach below. I hope these resources will help you as you progress with your project and let us know if you have any more questions, which I’ll try my best to answer.

Thanks,

Great! THANK YOU!

Of course! Good luck with your project!
