Question

Humans are aerobic in nature,that means they can live only in the presence of oxygen,.

But few microorganisms exist in anaerobic conditions,that means they can live with out oxygen..

Then why can't we insert the desired gene of that microorganisms into humans using biotechnology...

If we do so,then human can easily stay without oxygen?

Solution

Except for three species of anaerobic lorcifera, all the other multi celled organisms are aerobic in nature. Look closely , among all the anaerobic organisms that you find 90% of them would be in really harsh conditions (like the bottom of sea floor) where there is very less oxygen. Evolution made them anaerobic. Human beings undergo aerobic respiration and anaerobic respiration both. But most of the energy that is produced in our body is through aerobic respiration. Energy is produced through very complex cycles and bio chemical reactions and all these are results of various genes. So its an unimaginably difficut task as of our present knowledge to clone all the genes in our body. May be in future we may be able to achieve it. However the energy demands of such a large organism as human beings is much higher so anaerobic is just not enough.
