Describe the energy pathways that are available for cells living in the absence of o2.
00:05
In other words, what energy pathways can cells do if they have o2 deficiency, oxygen deficiency? so there's something called aerobic respiration and there's something called anaerobic respiration.
00:20
So an aerobic respiration is when you have no or very little oxygen.
00:25
So when you have very little oxygen, you can only do glycolysis and you do a little.
00:30
Specific type of glycolysis called fermentation.
00:34
So if you have eukaryotics like humans, then you do something called lactic acid fermentation and if you are bacteria or precarriotes you usually do alcohol or ethanol fermentation.
00:48
And so the way that glycolysis works is that essentially when you have your nadhs, they get converted back down to any, they become oxidized back to nad pluses...
