What is optimum condition for an enzyme?

every enzyme has specific optimum temperatures and pH.

1. The pH is very specific even a minor change of .5 will cause the enzyme to denature.

2. The temperature is less specific all enzymes will work below the optimum temperature but the reaction will be slower. Above the optimum temperature the enzyme will denature.

Note the optimum temperature of the human body is around 37.5 degrees C and the optimum pH is around 7.3.
