Graph of enzyme activity against temperature
Weban enzyme works as a catalyst. A graph of enzyme activity plotted against temperature is shown below. The enzyme in the graph above works most efficiently as a catalyst at 40 °C. This is the optimum temperature for this enzyme. Above 40 °C the enzyme begins to work less efficiently as a catalyst because the shape of the enzyme molecule starts ... WebGraph of average time taken(s) against temperature(ᵒC) Conclusion of experiment to show the effect of temperature on enzyme activity Temperature has an effect on enzyme activity. As temperature increases, enzyme activity increases making it work faster. The enzyme activity increases till an optimum temperature is reached, from then the ...
