Answer:
pH - Each enzyme has an optimal pH at which it works best, if the pH is too acidic or basic, the enzyme will start to denature.
Temperature - Each enzyme has an optimal temperature at which it works best as well. If it is too hot, the enzyme will start to denature and if it is too cold, there will be fewer collisions between enzymes and substrates.
