Approve or reject all formulations, procedures, specifications, test methods, controls and results that affect the purity, quality and composition of each ingredient and product written procedures shall be established and implemented. In high concentration it is toxic therefore, its accumulation in cells would be harmful most tissues, however, contain the enzyme catalase, which catalyzes the breakdown of peroxide to water and oxygen as follows:.

Changing the concentration of the enzyme will affect the rate of the reaction i predict that as we increase the concentration of the enzyme the faster the rate of reaction will be. Several factors affect the activity of enzymes (and other catalysts) including temperature, ph, concentration of enzyme, substrate, and products a particularly important reagent in enzymatic reactions is water, which is the product of many bond-forming reactions and a reactant in many bond-breaking processes. A investigation into the effect of inhibitor concentration on the enzyme catalase these two will be the only factors that can be varies as all other factors need to remain constant to produce a fair test with accurate and reliable results. Investigating the light dependent reaction in photosynthesis it is fairly easy to show that plants produce oxygen and starch in photosynthesis at age 14–16 students may have collected the gas given off by pond weed (for example elodea ) and tested leaves for starch.
