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. WebEnzymes with high Km's can be much faster in reaction velocity. Think of it as also rate of release of product when affinity is high.
