A combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat. A combustion reaction always has oxygen as one reactant.The second reactant is always a hydrocarbon, which is a compound made up of carbon and hydrogen. combustion reaction is when a substance reacts with oxygen and releases a huge amount of energy in the form of light and heat.

Another important effect of iron in heme metabolism is its role in the accumulation of uro-and hepta-carboxyl porphyrins in the liver known to occur in porphyria cutanea tarda (PCT). 14 Most patients with PCT have a moderate increase of liver iron, which seems to play a role in the pathogenesis of the disease.
Iron combines with certain proteins to become hemoglobin in your red blood cells. Iron is present in small amounts in the body. It carries oxygen to the body's tissues. Too little iron - and hemoglobin - can trigger an internal energy crisis because oxygen helps convert food into energy.
