Why does it take several redox reactions in a cell to make water from hydrogen and oxygen?

Answer

It takes several redox reactions in a cell to make water from hydrogen and oxygen because hydrogen and oxygen combine explosively when a single reaction

Explanation

Molecules of hydrogen react with oxygen violently to break the initial molecular bonds and form new one between the atoms of the two elements. The reaction results into an explosive release of energy and the production of water because the products of the reaction are at a lower energy level.
