【Haichuan Teahouse】Why haven’t animals evolved to breathe nitrogen?
Thread Content
As is well known, animals rely on oxygen for breathing. There is a curious question: since oxygen makes up 21% of the air, while nitrogen, which constitutes 78% of it, why isn’t it what animals need?
All biological activities in living organisms require energy, that is, oxidation that releases heat. Can nitrogen undergo an oxidation reaction?
It seems that rhizobia can fix nitrogen……
Then why can’t it be a nitridation reaction? ? ?
Does inhaling some nitrogen and carbon dioxide, along with drinking water, allow for the synthesis of proteins and fats? :D:P
That’s possible; it’s a good idea
There are anaerobic bacteria that can survive without oxygen.
Inert gases are too unreactive; the probability of them giving rise to life is **lower than that of O**
Then breaking this rule isn’t it what leads to a Nobel Prize?
If the nitridation reaction can release heat, it should also be possible
