Q1
An enzyme-catalyzed reaction shows a burst phase: rapid product formation in the first few seconds followed by a slower steady-state rate, despite constant substrate excess. A single-turnover experiment suggests chemistry is fast but a later step is slow. Which mechanism best explains the burst kinetics?
