Enzymes use several types of catalytic mechanisms. differentiate between acid-base catalysis, covalent catalysis, and metal ion catalysis.

Categorize the following into these four categories (acid -base catalysis, covalent catalysis, metal ion catalysis, and All)

- catalysts may participate in oxidation-reduction reactions by changes in the oxidation state
- a Zn^2+ cofactor may properly orient the substrate in the active site through ionic interactions
- may take part in interactions involving Fe^2+
- lowers the energy or stabilizes the transition state or intermediate
- catalyst retains its original form after reaction occurs
- a proton is transferred between enzyme and substrate
- a covalent bond forms between enzyme and substrate
- two-part catalytic process (for example, the chymotrypsin mechanism)
- uses a nucleophilic functional group
- may use amino acids such as aspartate or lysine for protonation of proton abstraction
