Describe the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme.

The effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.

An enzyme is a substance that acts as a catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process

Thus, the effect on an enzyme of an increase in environmental temperature above the optimum temperature range of the enzyme - denature the enzyme and lose the specific shape of the enzyme leads to losing its activity.

In an environmental temperature above optimum temperature will cause the enyzmes to denature (deform), because when they denature the subtrate will no longer fit into the enzyme
