Вот контекст:
The inhibition function considered here has a mirror effect to that of the saturation function. No effect on the substrate utilisation rate is seen at a null value of inhibitor concentration. At the half saturation constant concentration, the inhibition function value is 0.5 and the substrate utilisation rate is half of the maximum value. At nine times the half saturation value, the substrate utilisation rate is only 10% of its maximum and at an infinitely high inhibitor concentration, the substrate utilisation rate is completely inhibited. More details on inhibition are provided in Chapter 10.
А неясно мне, что в четвертом предложении означает At nine times the half saturation value. Помогите, пожалуйста!

А вы на график выше посмотрите (Figure 2.20).

At the half saturation constant concentration, the inhibition function value is 0.5 and the substrate utilisation rate is half of the maximum value. -->> K1 = 50, соответствует примерно 500 (= 50% = half of the maximum value) по правой вертикальной оси.

At nine times the half saturation value = 9 x 50 = 450 по горизонтальной оси, чему соответствует примерно 100 (= 10%) по правой вертикальной оси.
