C)random bisubstrate
D)simple unimolecular

Question

Quizplus · Accepted Answer

Enzymes carrying out covalent catalysis usually use the Ping-Pong kinetic mechanism. In this mechanism, the enzyme first binds to the substrate and transfers a chemical group to the enzyme, forming a covalent intermediate. The enzyme then releases the modified substrate and binds a second substrate, which reacts with the covalent intermediate to form the final product. This mechanism is called Ping-Pong because the enzyme and substrates alternate like a Ping-Pong ball.
