Below 1 is negative cooperativity, where as more than 1 is positive. Catalytic efficiency= kcat/km. … grand lucky scbd food courtWebThis can be arranged to (kcat/Km)[S]. So at low substrate concentration, kcat/Km gives an idea of how well the enzyme performs. In other words, a high kcat/Km ratio means the enzyme works well with not much substrate. This is called catalytic efficiency because if the enzyme is efficient, it means it doesn't need much substrate to achieve a ... grand lucky superstoreWebThis problem has been solved!
