TRUE:)
Each enzyme can catalyze a wide variety of different reactions.
This is a true statement. If an enzyme that is involved in DNA replication is not there, then a mutation can occur.
Enzymes are permanently changed by the reactions they catalyze
true
The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
