Optimum temperature for enzyme activity is 37 degrees Celsius (temperature of human body). Extreme low (around 0 degrees Celsius) and enzyme activity may not even happen at all. At extreme highs (45 degrees Celsius +) the enzymes are denatured and won't work at all.

The optimum pH for enzyme activity is 7 (neutral). Both sides, lower and higher, will gradually make enzyme activity worse as you go lower or higher around 7.

Hope that helps! Just been studying for an exam and I'm 100% sure that is all correct!
