Many biochemical reactions are catalyzed by acids.

Question

Many biochemical reactions are catalyzed by acids. A typical mechanism consistent with the experimental results (in which  HA is the acid and X is the reactant) is

Step 1: Fast, reversible HA = H+ + A-

Step 2: Fast, reversible X + H+ = HX+

Step 3: Slow HX+ = products
Which step controls the reaction rate?
