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 ... WebWhat effects do enzymes have on reaction rates? The activation energy of a chemical reaction is lowered by enzymes, also known as biological catalysts. ... Enzymes speed up chemical reactions in the body, but do not get used up in the process, therefore can be used over and over again. gears4car
