Which Is the Correct General Equation for an Enzyme-Catalyzed Reaction $\rightarrow$

Which is the correct general equation for an enzyme-catalyzed reaction? Enzyme is represented by "E," substrate by "S," and product by "P."

A) E $\rightarrow$ S + P
B) P + S $\rightarrow$ E + P $\rightarrow$ EP
C) S $\rightarrow$ E + P
D) E + S $\rightarrow$ ES $\rightarrow$ E + P
E) P $\rightarrow$ E + P $\rightarrow$ EP $\rightarrow$ S
