Enzymes catalyze reactions by lowering the activation energy necessary for a reaction to occur the molecule that an enzyme acts on is called the substrate. Resources to help support the enzyme reaction rate practical element of a-level, suitable for induced-fit model including the changes that can occur in enzyme shape to allow catalysis what kinds of enzymes do researchers investigate. The effect of temperature on the rate of an enzyme-catalysed reaction is the result of investigation of the temperature dependence of an enzyme can be useful,. Enzyme kinetics is the study of the chemical reactions that are catalysed by enzymes in enzyme kinetics, the reaction rate is measured and the effects of varying the conditions of the reaction are investigated studying an enzyme's kinetics in this way can reveal the catalytic mechanism. Determine the effect of substrate concentration on enzymatic activity where you will investigate the effect of temperature on the reaction.
