In an experiment involving an enzyme, the pit is raised from 2 to 11. What will be the most likely effect of

this increased pH on the reaction?

As we know enzymes are specific for different reactions and The conditions required by an enzyme to function are also specific. An enzyme which works in a basic environment will not be able to function in a acidic environment.

If the pH for a reaction is increased from 2 to 11 then this change will change the active site of the enzymes. As a result, the substrate will not be able to fit into the enzyme and hence the enzyme will not catalyze the reaction.
