Question 2
Identify each statement as true or false.
True False
1 2
Temperatures that are too high may Too many enzymes present in a solution
denature an enzyme. may denature the enzyme.
pH is determined by [H+] present in Lactose is an enzyme that breaks down
solution. lactase.
A low pH may denature an enzyme. As the concentration of a substrate in a
solution increases, the enzymatic activity
will always continue to increase.
