The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes.…

Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.

1) uncatalyzed reaction
2) reaction catalyzed by enzyme A
3) reaction catalyzed by enzyme B
