Final answer:
The equation A − PO4 + B → A + B − PO4 would be catalyzed by D. Lyases class of enzymes.
Step-by-step explanation:
The equation A − PO4 + B → A + B − PO4 would be catalyzed by D. Lyases class of enzymes.
Lyases are enzymes that catalyze the breakage of a compound into two substances without the addition of water. In the given equation, a bond is broken resulting in the formation of a double bond (−) in one of the products, which is a characteristic of lyases.
