The temperature at which an enzyme-catalysed reaction proceeds fastest under the conditions being investigated.
Revise: Enzyme action and investigating pHAs temperature rises towards the enzyme's optimum temperature, molecules gain kinetic energy and move faster. More successful collisions occur each second, increasing the reaction rate. The optimum is the temperature at which the reaction is fastest under the conditions being investigated.
