WebSince the Michaelis-Menton constant Km is the concentration of substrate at 0.5Vmax, it is an inverse measure of its substrate affinity, because a lower Km indicates that less … WebKm may indirectly indicate substrates affinity towards enzyme. It has a value of substrate concentration at which velocity of enzyme is half of its Vmax. If the value of Km is high more substrate will be required to achieve 1/2 Vmax while when its value is low the 1/2Vmax will be achieved at lower substrate concentration.
