Question

Which of the following can you correctly infer from the graph about how the pH affects the enzyme's role in the target chemical reaction?

Rate of enzyme action
0 1 2 3 4 5 6 7 8 9 10 11 12 13
pH
There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy.
Increasing the pH makes it easier for the enzyme to lower the activation energy of the target reaction.
As the pH increases, the activity of the enzyme to lower reaction activation energy is decreased.
The enzyme will not assist the chemical reaction at a pH that is below 6 or above 12.

Answer 1

There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy.

Step-by-step explanation:

I got it right on the test.

Answer 2

The correct answer is There is a specific pH range in which the enzyme effectively lowers the reaction"s activation energy.

Step-by-step explanation:

There is a specific pH at which the an enzyme functions best is known as optimum pH.

Enzymes lowers the reaction"s activation energy but only at specific pH(optimum pH).If pH is increased or decreased the degree of ionization of various amino acids such as histidine,serine,glutamic acid present in the enzyme"s active site will be changed thus affecting the enzyme"s activity.
