How the temperature of hydrogen peroxide and yeast affects the rate at which they react Chemical Equation: Catalase Hydrogen Peroxide Water + Oxygen H2O2 H2O + O2 Introduction: Hydrogen Peroxide is an extremely dangerous waste product which it generated and degraded in small membrane-bounded organelles called Peroxisomes in the cells of our bodies. An enzyme, which is made up of proteins, called catalase has the specific job of breaking down the Hydrogen Peroxide in the body. The Lock and Key hypotheses states that enzymes are specifically designed to work on only one substance. We use the alginate to trap the yeast cells so we have immobilised the catalase that is present in the cytoplasm of the yeast cells. Also it is very useful to trap the enzyme as then we can visually record the rate of reaction by timing the ascent of the bead due to the oxygen bubbles forming and sticking to...
