Which of the Following Determines the Enzymatic Reaction Rate

Question

Which of the following determines the enzymatic reaction rate?
A)the difference in energy between ES and S
B)the difference in energy between ES and P
C)the difference in energy between ES and EX‡
D)the difference in energy between ES and ESI

Accepted Answer

The enzymatic reaction rate is determined by the difference in energy between the enzyme-substrate complex (ES) and the transition state (EX‡). This energy difference influences the activation energy required for the reaction to proceed, directly affecting the reaction rate.
