Changing the tempreture can change the rate of the catalyst BUT
If it gets too hot bonds holding the enzyme together break, destroying the enzymes shape.
This is called denaturing
Enzymes in the human body work best at 37 C
The ph can also affect enzyme bonds, they normally work best at the neutral ph of 7, anything above or below it will start to denature.
But this isn't always!
An emzyme in the stomach to break down proteins works best at ph2, meaning its well suited for acidic condidtions.
All enzymes have an optimum point temperature and ph, this is where the enzyme works best at, anything above this the enzyme will start to denature.
