Great Video! If I may ask, what source did you use for this video? I would like to read more aboute this topic.

Of course, here are some sites where you can read more about this topic: 1. Apoptotic Cell Death Under Hypoxia: journals.physiology.org/doi/full/10.1152/physiol.00016.2013 2.Hypoxic environment: www.sciencedirect.com/science/article/abs/pii/S1546509808000010 3.I also mentioned ion pumps in the video: www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/ion-pump 4.Cell cycle progression in response to oxygen levels: pmc.ncbi.nlm.nih.gov/articles/PMC4143607/ Hope that was helpful!

@microbesmatter999 Thanks a lot!

Your video are very well made and beautiful. I have only one question: why, in many of the previous videos, you used qm as symbol for micrometer, instead of the correct one (μm) or maybe the less-correct but common um (used often when the Greek letter μ isn’t available)? The prefix q in fact exists in the SI system, but it means 10 to the power of -30, so a qm is a quectometer, 24 order of magnitude smaller than a micrometer… See: en.wikipedia.org/wiki/Orders_of_magnitude_(length)#1_quectometer_and_less Now I see that you started using μm recently, but I always wanted to ask you :) Still, beautiful videos really.

Thanks! And to be honest, I couldn ' t find the correct " μ" on my keyboard! Now I realised that I was wrong the whole time and fixed it, and thanks to you I also know what it really stands for now :)
