E) They are unaffected by changes in pH.

Question

Quizplus · Accepted Answer

Enzymes are highly specific and generally catalyze only one specific type of reaction. This specificity is based on the enzyme's unique 3-D shape, which allows it to interact with a specific substrate in a precise manner. While enzymes can associate with a wide variety of substrates, they will only catalyze the reaction for which they are specifically designed. Temperature, pH, and other environmental factors can also affect enzyme activity.
