Describe two important features that make all enzymes catalysts. How are enzymes affected by heat? What are the main characteristics of enzymes? How do enzymes work? a. They can change the shape of a substrate t
Why are enzymes important to the human body? Catalysts: Catalysts are substances that speed up the rate of a chemical reaction. They do this by lowering the energy barrier, called the activation energy, for a reaction to occur. In the process, the catalyst is not changed so it does not ...
