You will now perform a simulation looking at the effects on enzyme activity of changing pH or substrate molecule concentration.

Your objectives will be to

• determine the effect of substrate concentration on the initial rate of an enzyme-catalyzed reaction
  
  
• determine the effect of pH on the initial rate of an enzyme-catalyzed reaction

You will follow the procedure outlined in the simulation. 

Start simulation

You need to be comfortable with graph interpretation for this and future topics. For more information on graphing, visit the graphing pages in the Tutorial section found at the start of your course.
