Final answer:
Enzyme denaturation is the process when enzymes change shape and can no longer catalyze a chemical reaction. It can be caused by factors such as high temperatures or changes in pH. An example is the cooking of egg whites where heat denatures the proteins.
Step-by-step explanation:
When enzymes change shape and can no longer catalyze a chemical reaction, this process is called enzyme denaturation. During this process, the enzyme loses its specific shape and hence loses its ability to bind to the substrate and catalyze the reaction. Denaturation can be caused by various factors such as high temperatures, changes in pH, or exposure to certain chemicals. An example of enzyme denaturation is the cooking of egg whites where heat denatures the proteins causing the liquid egg whites to become solid.
