The initial rate of an enzymatic reaction is usually determined in order to assure that
A) the enzyme is active
B) there is no reverse reaction of product to the enzyme-substrate complex
C) the substrate is not used up
D) the experiment can be completed quickly

Question

Quizplus · Accepted Answer

The initial rate is measured to ensure that the concentration of the substrate is high enough that the reverse reaction (product converting back to enzyme-substrate complex) is negligible, allowing for accurate measurement of the forward reaction rate.
