What happens when boil an enzyme?

Hi Gemz,
Enzymes are essentially functional proteins. It all depends on the protein (enzyme) and the water temperature. Up to a certain point the reaction of the enzyme will be accelerated, but much beyond that and the enzyme will begin to denature, losing its characteristic structure and ceasing to be any longer functional.

It depends
If the optimum temperature of the enzyme is low,then it will be denatured
But if it has got a high optimum temperature then nothing much would happen
For example: Taq thermus aquatica is a strain that is isolated from hot springs
Can survive at 95C as it is adapted to this range

All the human body enzymes will surely be denatured
