The production of oxygen can be seen by the formation of bubbles . This easy test, which can be seen with the naked eye, without the aid of instruments, is possible because catalase has a very high specific activity, which produces a detectable response, as well as the fact that one of the products is a gas . </P> <P> While the complete mechanism of catalase is not currently known, the reaction is believed to occur in two stages: </P>

How can you tell if an organism has the enzyme catalase upon treating it with hydrogen peroxide
