Question

Enzymes use several types of catalytic mechanisms. Differentiate between acid-base catalysis, covalent catalysis, and metal ion catalysis. (If you answer any part of this question incorrectly, a single red X will appear indicating that one or more of the phrases are sorted incorrectly.)

Acid-base catalysis Covalent catalysis Metal ion catalysis All uses a nucleophilic two-part catalytic process functional group (for example, the catalysts may participate in oxidation-reduction reactions chymotrypsin mechanism by changes in the oxidation state a zn2+ Cofactor may properly orient may take part in lowers the energy or catalyst retains interactions stabilizes the transition its original form the substrate in the active site involving Fe state or intermediate after reaction occurs through ionic interactions a covalent bond may use amino acids such as a proton is transferred between forms between aspartate or lysine for enzyme and substrate enzyme and substrate protonation or proton abstraction
