Enzymes are made of protein and a non protein therefore they can not be denatured? true or false?

False , because as I think that all the enzymes are made up of protein and they are acting as as a biological catalyst which speed up the reaction therefore they can denature by many factors the essential Factors r temperature and pH or the acidity some of the enzymes denature at pH of 2 and a high temperature of 40 degrees Celsius but some of that enzymes become more active or optimum at a temperature of 37 degrees celsius and at a ph of 7
