A decomposition reaction occurs between catalase and hydrogen peroxide, where catalase speeds up the breakdown of hydrogen peroxide into oxygen and water. The general equation for the reaction is 2H2O2 - 2H2O + O2. More »

According to Reference.com, catalase can be found in most living cells, which means this enzyme that causes hydrogen peroxide to decompose into oxygen and water is not contained in all living tissues. The origin of the w... More »
