These factors are: - temperature - ph - enzyme concentration - substrate concentration - inhibitor increasing the enzyme concentration beyond a certain point does not change the rate of reaction (d) [pa] investigate and explain the effects of temperature, ph, enzyme concentration and substrate. The catalase is really effectual 50 % enzyme green goods less bubbles and respond slower with h peroxide compared to 100 % enzyme concentration however, the rate of reaction will be relative to the enzyme concentration if the substrate concentration is high plenty and the temperature and ph. Factors effecting catalase rate of reaction temperature, ph, substrate concentration, enzyme concentration, inhibitor concentration (ex ammonia) if yyou are reacting a soild and a liquid and yyou varyy the concentration of the liquid then generallyy the rate of reaction will increase because.

The catalase acts as lowering activation energy to make reaction faster as usual and give effect to hydrogen peroxide to gain more energy to break the bond in order to overcome the enzyme work optimumly at certain ph and temperature substrate concentration also affects the rate of reaction. Effects of temperature, ph, enzyme concentration, and substrate concentration on enzymatic activity introduction enzymes, proteins that act the higher concentration of reactant, the faster the rate of the reaction in this experiment, hydrogen peroxide acts as substrate and the catalase in.
