These conditions are not the same for every enzyme, for example some enzymes may have a higher tolerance to heat and may not denature at the temperatures at which tyrosinase denatures. Since enzymes can only function properly under certain environmental conditions, it is extremely important that organisms provide such conditions to maintain their functions. As a result organisms are limited to what they can ingest and where they can live, for example ingesting an extremely basic or acidic solution could cause enzymes in the stomach to fail
