## 概述

Interactive visualization of enzyme kinetics and Michaelis-Menten kinetics - Explore Michaelis-Menten equation (v = V_max·[S]/(K_m + [S])), Lineweaver-Burk double reciprocal plot (1/v vs 1/[S]), reaction mechanism (E + S ⇌ ES → E + P), inhibition types (competitive, non-competitive, uncompetitive), reaction coordinate diagram showing activation energy reduction by enzymes, and real-time enzyme-substrate complex formation animation. Features adjustable parameters: V_max (maximum velocity), K_m (Michaelis constant), substrate concentration [S], inhibitor concentration [I], inhibition constant K_i, and animation speed. Includes multiple visualization panels: (1) Michaelis-Menten Plot showing velocity vs substrate concentration curves with V_max asymptote and K_m indicator; (2) Lineweaver-Burk Plot displaying double reciprocal linear plot with slope, intercepts, and inhibition pattern comparison; (3) Reaction Mechanism Animation showing enzyme (E), substrate (S), ES complex formation, and product (P) release with molecular collision dynamics; (4) Reaction Coordinate Diagram comparing activation energy with and without enzyme catalysis. Real-time value displays: current velocity v, V_max, K_m, apparent K_m and V_max under inhibition, slope and intercepts for Lineweaver-Burk plot, activation energy reduction. Educational content covers enzyme kinetics fundamentals (Michaelis-Menten theory, steady-state approximation, rapid equilibrium assumption), K_m significance (substrate concentration at half V_max, enzyme-substrate affinity measure), V_max definition (k₂·[E]_total), catalytic efficiency (k_cat/K_m), inhibition mechanisms (competitive: active site binding increases K_m; non-competitive: allosteric binding decreases V_max; uncompetitive: ES complex binding decreases both), rate constants (k₁ for binding, k₋₁ for dissociation, k₂ for catalysis), and applications in drug development (enzyme inhibitors as pharmaceuticals), clinical diagnostics (enzyme level measurements), biotechnology (enzyme optimization), metabolic engineering, and toxicology. Perfect for biochemistry education, understanding enzyme catalysis, and learning about enzyme inhibition patterns for drug design.
