Is there any alternative to Oxygen yet? what if we totally run out of it?

Answer 1

There is no alternative, and if we run out we die, but don't worry much of the water in the world could be converted to oxgygen, even if all the plants were dead.

Answer 2

Cellular respiration requires oxygen to properly metabolize glucose, which is a monomer from the break-down of macromolecules found in our food. i.e. sucrose (table sugar), starch (alpha glucose), lactose (in milk: lactose intolerant people lack lactase (enzyme needed to break down lactose)).

glucose + O2 yields H2O + C02 (this reaction occurs in all our bodies cells that possess a microscopic organelle called a mitochondria). If you take O2 out of the equation, we die since, all the O2 you inhale is shipped via the blood to the cells and used, and converted to C02 which you exhale.

Plants that possess chlorophyll stacked in cellular organelles called chloroplats do an opposite reaction then the one stated above.
sunlight + C02 + H20 yields O2 + glucose

So as long as we have green plants around in a sufficient quantity we should be ok.

But i heard it takes 3 trees/person to have an enough O2.
So plant trees!!!!

cheers

Answer 3

What u suggest is already taken care of. There is 20.9 % O. 1.1 % green house gas. 78 % N. There is a trick most people don't know. When Nitrogen is bombarded with alfa particles it will trans mutate to Oxygen. that means 20.9 plus 78 = 98.8 % oxygen is available.

Answer 4

Plants and trees put O2 into the air. Plant lots and lots of trees. If everyone on this site would plant even one tree, look at the difference we could make...

Answer 5

we're doomed.
