WebThe following, therefore, is the correct explanation of what happens when an enzyme denatures: a change in the protein structure of an enzyme causes a change in the shape of the active site. We are now going to look in more detail at how temperature, pH, and substrate concentration affect the rate of enzyme activity. WebIn biochemistry terms the difference between enzyme and substrate is that enzyme is a globular protein that catalyses a biological chemical reaction while substrate is what an …
