Answer:
- Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis
- As the pH decreases below the optimum, enzyme activity also decreases.
Answer: Enzymes function within a large pH range.
- Too much change = Not good, so there isn't a BIGGG range.
