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?

A line graph showing rate of enzyme action versus pH. The graph indicates pH on the x-axis with a numbered line increasing to the left. The graph also indicates the rate of enzyme action as it increases on the Y-axis. A line starts at approximately 4.5 on the x-axis and climbs to a steep peak at approximately 9 on the x-axis. The line then declines at the same rate and levels out to its starting position at approximately 13 on the x-axis.

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

I just wanted to say the top person is correct, i just took the test and got it right, but i couldn't comment.

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

Answer 2

I'm going to say since I cannot see the graph i'm guessing that it shows an enzyme at its peak and lowering so i'm going to say the first one 1) There is a specific pH range in which the enzyme effectively lowers the reaction's activation energy

Step-by-step explanation:

i hope this helps
