WebGraphically, the K m is the substrate concentration that gives the enzyme one-half of its V max. Although it may look like the V max drops, if the graph is extended along the x-axis, the V max stays constant for the two enzymes described here. The table shows the K m and V max of some common enzymes. WebTranscript The units of the rate constant, k, depend on the overall reaction order. The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and …
