What happens to the enzyme activity of A after 30 degrees

The temperature of Enzyme activity of A is affected because the rate of an enzyme catalyzed reaction increases when temperature is raised.

Explanation:

The temperature can affect the enzyme in two different ways they are direct influence on the reaction rate constant and the thermal denaturation of the enzyme at elevated temperatures.

In an optimum condition there is a higher rate of reaction which states there is a lower Km and higher Vmax value. In lower temperature the Km value increases resulting lower affinity of substrates with the enzymes. The lower activity is due to the lower affinity of the substrates with the enzyme.

If the temperature is rised to ten degree then the activity of enzymes are increased to 50 to 100 %.
