Based on the graph above, how well will the enzyme perform as a catalyst when placed in a pH 7 solution, such as water?
mrs_skeptik [129]
The correct answer is "<span>It will perform less than optimally unless the pH was increased."

This is because the curve on the graph shows pH versus reaction rate. If we follow the x-axis (the bottom one) to a pH of 7, it is at an extremely low reaction rate compared to other points of the graph. If we continue along, we see that the reaction rate increases as the pH increases. Therefore, the enzyme will perform less than optimally unless the pH is increased.

Hope this helps, and hope I'm the brainiest! :)</span>
