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

If you have ever seen hydrogen combine with oxygen directly you will remember that an explosion was involved. In classroom situations the amounts of the two gases used are very tiny and the explosion is safe but violent reactions like this cannot be allowed in a living cell. The other thing to note is that it was necessary to use a spark to set off the explosion. Again, this would not be possible in a living organism. All of the reactions in a cell have to be done in such a way as to cause no damage. Hence, the need for several steps.
I almost forgot: when the reaction between hydrogen and oxygen occurs if the energy provided is needed by the cell (or even if it isn't) the cell must have a way of capturing it in a useful form. There would be no point in releasing energy and allowing it to go to waste.

Which statemment is not true of most cellular redox reactions?
A hydrogen atom is transferred to the atom that loses an electron.
What happens to electrons in a redox reaction?
Electrons may be transferred from one particle to another.
Why only oxygen supports combustion and not hydrogen or nitrogen?
Hydrogen is not electronegative enough to act as a strong oxidizing agent, and the triple bond in the N2 molecule is difficult to break, making the gas largely inert. However, the halogens, particularly fluorine and chlorine can support redox reactions similar to combustion.
The reactions taking place inside a lead accumulator are said to be redox reactions describe the chemical reaction and justify the statement?
redox reactions means which involves both oxidation and reduction reactions reactions.
Which two reactions are also redox reactions combustion and single-replacement combustion and synthesis synthesis and decomposition single-replacement and double-replacement?
All of them can be redox reactions.
Why does it take several redox reactions in a cell to make hydrogen and oxygen?
Hydrogen and oxygen combine explosively in a single reaction.
Why does it take several redox reactions in a cell to make water from hydrogen?
Hydrogen and oxygen combine explosively in a single reaction.
Why does it take several redox reaction in a cell to make water from hydrogen and oxygen?
Without getting into the specifics of the electron transport chain, redox reactions are needed because electrons need to be shuffled around to provide the right conditions for the oxygen and hydrogen to combine. After respiration, there are many hydrogen ions (protons) sitting around while "their" electrons are being passed back and forth in continuous redox reactions. The very last redox reaction is when the electronegative oxygen accepts the electrons -- then four hydrogen ions come in to bond with O2 to make two water molecules.

In the redox reactions of cellular respiration a cell uses?
A cell uses both glucose and oxygen in the redox reactions of cellular respiration.
In the redox reactions of cellular respiration a cell of uses both?
A cell uses both glucose and oxygen in the redox reactions of cellular respiration.
In the redox reactions of cellular respiration a cell uses oxygen AND?

Why burning of fuel in oxygen and rusting of iron are considered as redox reaction?
There is a transfer of electrons during both reactions and that is what a redox reaction is.
Which statemment is not true of most cellular redox reactions?
A hydrogen atom is transferred to the atom that loses an electron.
Where does Redox occur in bacteria?
The Redox 'Battlefield' is the Redox reactions mediated by bacteria.
What materials will rust?
Rust is the result of a metal reacting with oxygen in a moist environment in a redox reaction. Some of these redox reactions happen spontaneously, others need some extra energy. The reactions that don't require additional energy will happen on their own.
