The rate of an enzyme reaction (V) varies with the substrate concentration, increasing with an increased concentration until a maximum value (Vmax) is reached. At this point, all enzyme molecules are fully occupied and the rate of reaction is limited by the rate of the catalytic process on the enzyme surface. For most enzymes, the concentration of substrate at which the reaction rate is half maximal (Km) is a measure of how tightly the substrates are bound, with a large value of Km representing a weak binding, and vice versa. 3, record 4, English, - concentration

Il existe des réactions d'ordre zéro, du premier ordre, du deuxième ordre et du troisième ordre, suivant la nature de la relation entre la vitesse de la réaction et la concentration d'un des réactifs dans des conditions données. La vitesse de certaines réactions chimiques est indépendante de la concentration des réactifs : on les appelle réactions d'ordre zéro. Beaucoup de réactions catalysées sont d'ordre zéro vis-à-vis des réactifs. Dans ces cas, la vitesse de réaction dépend de la concentration du catalyseur ou de divers facteurs autres que la concentration des composés chimiques qui entrent en réaction. Les réactions du premier ordre sont celles dont la vitesse est exactement proportionnelle à la concentration d'un réactif. Les réactions du deuxième ordre sont celles dont la vitesse est proportionnelle au produit des concentrations de deux réactifs différents, ou au carré de la concentration d'un seul réactif. Les réactions du troisième ordre, relativement rares, sont celles dont la vitesse est proportionnelle au produit de trois concentrations. 3, record 4, French, - concentration
