How is the activity of an enzyme is regulated? How does pH affect an enzyme? How does substrate concentration affect the speed of enzymatic reactions? What are some factors that affect enzyme activity? How does changing the pH affect the rate of enzyme activity?
When the pH value falls outside of the optimum range, the enzyme's activity slows and eventually stops. The active site of the enzyme is located at the substrate-binding site and the shape of the active site changes when the pH value changes. These alterations may irreversibly "destroy" the...
What is the effect of substrate concentration on enzyme activity? How do enzymes affect reactions? Explain the effect of water on enzyme function. Why does altering the pH of an enzyme's surroundings sometimes cause the activity of that enzyme to be changed? A. strong acids can turn the prot...
