Organisms lacking the cytochrome system also lack the catalase enzyme and are unable to break down hydrogen peroxide, into O 2 and water and are catalase negative. Catalase activity is very useful in differentiating between groups of bacteria.rganisms capable of producing catalase rapidly degrade hydrogen peroxide which is a tetramer containing four polypeptide chains, which are usually 500 amino acids long. It also contains four porphyrin heme groups(ie., iron groups) that will allow the enzyme to react with the hydrogen peroxide.
What year did Bohr find that electrons can jump from a path in one level to a path in another level? He came up with his model of the hydrogen atom, containing this idea, in 1913. That's almost exactly 100 years ago.
Best Answer: What it means is that there is one electron in the atom that is elevated to an energy level above the ground state. In H that would be it got kicked up to 2s or 6p THe electron in the elevated state is prone to fall back to its ground state, giving up the energy.
