I believe these are all right correct me if I am wrong
If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.
Since enzymes function as organic catalysts, a cell would not be able achieve homeostasis if the required enzymes were not present.
both plants and animals can if that helps. So any living being I think...
