The energy needed in the basic reaction in bacteria’s production of light is taken from the bacterial cell’s ATP. Oxygen binds to a molecule known as luciferin and forms a new molecule. The marvelous thing here is that light is produced as a byproduct of this reaction.
This formula, that someone without a knowledge of chemistry will likely not understand, is only a brief summary of the light production system in bacteria.
The chain of reactions that take place during light production may well be compared to a clockwork mechanism functioning with a number of interconnected cog wheels. The chemical reaction, whose formula is given above, takes place where these cog wheels touch one another. However, in order for there to be constant light emission, the molecules used also have to be restored to their original forms because these molecules are consumed by being turned into other molecules, like a candle burning down. The chain reaction, functioning like cog wheels, enables molecules to return to their original forms.
The majority of processes requiring continuity in the cells take place with these cog wheels, as it were, being literally turned into one another by such molecular systems.
As we have seen, many various components need to be present together for light production. When these components are present at the right time, in the right place and perform the right processes, the result is a most superior product – the manufacture of light.
Just one flaw in the components in this system, or the absence of just one enzyme involved in the process, or the slightest error in their architecture, will halt this system of production. This is like damage to one of the clock's cog wheels impairing the functioning of it.
In the same way that it is impossible for a clock consisting of cog wheels all working together in harmony to emerge by chance, so the light produced by the chain reaction made up of biological cog wheels cannot be the work of chance, either.
The amazing miracle of light in living things is part of the artistry of Allah, and one of the proofs of His infinite might and omniscience.
Another amazing point is that all these reactions and processes take place in micro-organisms just 0.001 millimeters (3.93700787 × 10-5 inches) in size. There is no doubt that the way this perfect system is packed into such an extraordinarily small space shows that these organisms are created by Omniscient and Almighty Allah.
