Catalysis is about the breakage and making of bonds. In other words, there is a formation, reformation, and rearrangement of atoms and molecules. An example of catalysis is the process of breathing, where hemoglobin molecules combine with the oxygen to form the heme complex. The combination is an example of coordinate bonding that involves partial interaction. However, other interactions like hydrolysis of sugars by enzyme involve hydrogen bonding.
Thus, catalysis is hydrogen and ionic bond formation and breakage.
