Enzyme‐catalyzed conversion of substrate S to product P is modeled by E + S ⇌ ES → E + P, with microscopic rate constants k1, k−1, and k2. Let Et = \[E] + \[ES] be the total enzyme concentration, typically ≪ \[S]. Under initial-rate conditions (t → 0, negligible back reaction from P), the Briggs–Haldane steady-state assumes d\[ES]/dt ≈ 0 because ES forms and breaks at ____ ____ ___ _______ ___ _________ ____ ____ _____.
