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 is necessary for the construction of, and is actually part of, the hemoglobin molecule. Hemoglobin is necessary for the transport of oxygen around the body. Iron is a necessary part of myoglobin, the red protein in muscle cells. It also is used as a co-factor/mineral to enzymes involved in growth.ron is necessary for the construction of, and is actually part of, the hemoglobin molecule.
