Enzyme Activity and pH Levels

What happens to an enzyme if it is exposed to a mild pH change away from its optimum?

• It becomes permanently denatured.

• It becomes more active.

• It stops functioning immediately.

• It may not denature and can still function.

How can extreme pH levels, like those in the stomach, affect an enzyme?

• They enhance the enzyme's activity.

• They have no effect on the enzyme.

• They can permanently denature the enzyme.

• They temporarily deactivate the enzyme.

What role do internal bonds play in enzyme functionality?

• They only affect the enzyme's color.

• They determine the enzyme's shape and function.

• They are only important in antibodies.

• They are irrelevant to enzyme function.

What can happen if the internal bonds of an enzyme are permanently altered?

• The enzyme becomes resistant to pH changes.

• The enzyme changes color.

• The enzyme loses its shape and function.

• The enzyme becomes more efficient.

If the pH is restored to its optimum level, what can happen to an enzyme?

• It changes its optimum pH.

• It can regain its functionality.

• It remains denatured.

• It becomes inactive.
