Question

In parallel kinetic enzyme assays, how is the initial reaction velocity ($V_0$) accurately determined?
Options
A By measuring signal linear rate of change at the earliest reaction timepoints where substrate depletion is negligible.
Correct Answer
B By measuring total product absorbance after reaction completion at equilibrium.
C By averaging product concentration at zero minutes and overnight incubation.
D By dividing total substrate concentration by the molecular weight of the enzyme.
Correct Answer

Option A is the correct answer.

Detailed Explanation

$V_0$ must be derived from the initial linear phase of the reaction before substrate concentration drops significantly or product inhibition occurs.
