Q. Choose the correct options
A) E + S $\rightarrow$ ES $\rightarrow$ E $+$ P $\rightarrow EP$
B) E + S $\rightleftharpoons$ ES $\rightarrow$ E $-$ P $\rightarrow$ E + P
C) E + S $\rightarrow$ ES $\rightleftharpoons$ E $-$ P $\rightarrow$ E + P
D) E + S $\rightleftharpoons$ ES $\rightleftharpoons$ E $-$ P $\rightleftharpoons E + P$
Explanation
Each enzyme [E] has a substrate [S] binding site in its molecule so that a highly reactive enzyme substrate complex [ES] is produced. This complex is short lived and dissociates into its product and the unchanged enzyme with an intermediate formation of the enzyme product complex [EP] The formation of the ES complex is essential for catalysis $E + S \rightleftharpoons Es \longrightarrow E - P \longrightarrow E + P$
