Question

Explain how increasing temperature affects enzyme activity.

Answer 1

As the temperature increases, so does the rate of reaction. But very high temperatures denature enzymes. The graph shows the typical change in an enzyme's activity with increasing temperature. The enzyme activity gradually increases with temperature up to around 37ºC, or body temperature.

Answer 2

Following is the explanation of how increasing the temperature, affects the enzyme activity.

• When the temperature is increased, the enzyme activity and the reaction rate both increase.
• Whereas, reducing the temperature leads to slowing down the activity of the enzyme.
• This is because each enzyme works best when they attain its maximum tolerable temperature.
• Similarly, the activity of the enzyme starts decreasing below its level of the optimum measured temperature.
• It is important to note that an enzyme gets denatured when the temperature is increased beyond its specific optimum level.

Hence, the above factors explain how increasing the temperature, affects enzyme activity.
