WebV_ {max} V max is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V_ {max} V max is called the K_m K m, and is a useful measure of how quickly reaction rate increases with substrate concentration. K_m K m is also a measure of an enzyme's ...
