6. Draw sketch graphs for enzyme activity with a competitive inhibitor present and for a non-competitive inhibitor present.

9. A B C D Enzyme-substrate reaction Competitive inhibition Non-competitive inhibition Co-factor

10. What would the effect of each of these conditions be on the activity of an enzyme? Increasing temperature within the normal range Decreasing pH Decreasing substrate concentration Increasing enzyme concentration Increasing concentration of a non-competitive inhibitor Increase in the surface area of substrate Decreasing concentration of a competitive inhibitor An increase of temperature above normal limits An increase in product concentration The activity of a different enzyme
