The enzyme activity was measured by five different temperatures, separated in tubes which later got measured by their height of foam after 10 minutes. Freshly-prepared potato juice was used as the enzyme for catalase. Since temperature is measured by the kinetic energy of molecules, the higher the temperature, the more movement of molecules. The lowest temperature makes it…
