Enzymes are large proteins that can act as a catalyst for chemical reactions or be used to break down large molecules into smaller ones.

Organisms have a number of different enzymes that control the chemical reactions that take place inside the cytoplasm.

Digestive enzymes are used to break down large insoluble food molecules into small soluble molecules.

Enzymes can be denatured if the temperatures are too high or the pH is too extreme. Different enzymes have a different optimum temperature and optimum pH.

Enzymes have an optimum pH at which they work best. If the pH is far from this optimum value the enzyme will denature.


This graph shows the optimum pH for amylase.
