why do carbon based organisms breathe oxygen when there is a

Oxygen is more apt at accepting electrons during metabolism, and creating a waste product of water.

Nitrogen is inert

Ain't no fucking with that crazy low energy bond order of 3 dinitrogen senpai. Also oxygen more electronegative easier to reduce, other reasons too but far too much to explain

>>7785554
This is bait.

Bacteria are carbon based organisms that can reduce dinitrogen to ammonia using nitrogenase. Only under anaerobic conditions though.

Why do organisms use chemical reactions as an energy source? Surely it would have been a better evolutionary trait to have an internal sustainable fusion reactor instead? Also, why do organisms need to be in a certain temperature range to survive? Surely it would have been a better evolutionary trait to live in all temperatures?

>Surely it would have been a better evolutionary trait to live in all temperatures?

certain necessary reactions happen at a determined temperature, too low temp and it wont happen, too high and you denature the proteins for example

Are you really this fucking dumb?

there are no dumb questions, anon

also calm down, no need to be such an autist :^)

Except he didn't pose a question, he made an idiotic remark with all the knowledge of a high school biology student.

>>7785863
if youre going to be autistic about it, it was technically a question, even if it was idiotic, question nonetheless

your reacting like an asperger's ridden imbecile is not excusable, however. now go back to your anime, fucking autist

Why does everything have to be evolutionary? Oxygen is just better at providing what is needed for organisms than nitrogen is.

And organisms evolved to breathe oxygen effectively because of that
