Question

mini - quiz: ph and enzymes
based off of your observations of the enzyme shown, which of the following is true?
a. the denaturation of this enzyme by ph changes is irreversible. in other words, restoring the ph to an optimal level does not fix the enzymes shape.
b. the denaturation of this enzyme by ph changes is reversible. in other words, restoring the ph to an optimal level does fix the enzymes shape.
c. the denaturation of the enzyme does not affect the enzymes function.
d. the denaturation of the enzyme is necessary in order for the enzyme to work properly.

Explanation:

Enzyme denaturation by pH changes can be reversible in some cases. When the pH is restored to the optimal level, the enzyme's shape can be fixed. Denaturation usually impairs enzyme - function and is not necessary for proper enzyme function.

Answer:

B. The denaturation of this enzyme by pH changes is reversible. In other words, restoring the pH to an optimal level DOES fix the enzyme's shape.
