WebApr 12, 2024 · Additionally, we observed a slower reaction profile compared with the standard reaction with weaker intensity of light (25% W, 50% intensity corresponding to ∼50% reactivity, see supplemental information for more details), suggesting that the iron-catalyzed decarboxylation might be a light-dependence process. Together, these results … 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 ...
