O = HCO. Carbonic anhydrase is the enzyme that catalyzes the chemical reaction that makes carbonic acid (H2CO3). Hydrase is related to the word 'water' while the an- suffix means 'without' therefore meaning without water. Anatomy & Physiology. © copyright 2003-2020 Study.com. 1. The reason for the reactions being in opposite directions for the tissues and lungs is because of the different pH levels found in them. Some reactions can be fairly exothermic but still extremely slow, simply because the activation energy is so high. Without the enzyme, carbonic anhydrase, the amount of activation energy is very large. What Is the Mechanism of Enzyme Activity?

In water, without the enzyme, the reaction proceeds with a rate constant of 0.039 s-1 at 28 degree C . True or false? The rate of a reaction is governed by a few factors: the frequency of collisions between reactants, the orientation of the collisions, and the activation energy of the reaction itself.
