WebPositive and negative effectors can affect the affinity of the enzyme for its substrate (K0.5), modify the maximal catalytic activity of the enzyme (V max), or both (Figure 5.16). [Note: Allosteric enzymes frequently catalyze the committed step early in a pathway.] Figure 5.16 Effects of negative positive WebA small Km also indicates that the enzyme requires only a small amount of substrate to become saturated. Hence, the maximum velocity is reached at relatively low substrate concentrations. A large Km indicates the need for high substrate concentrations to achieve maximum reaction velocity. The Km is independent of the enzyme concentration.

WebMore enzyme = higher Vmax. First Meaning of Km. (the Michaelis-Menten constant) is a type of equilibrium constant. Like [S], Km is reported in units of concentration (e.g. Molarity). … Web(When enzyme catalysis does not follow Machaelis-Menten kinetics, K0.5 instead of Km is used to describe the [S] when V0 = Vmax/2) Choices.

WebFeb 2, 2024 · The only difference between the Km and Kd expressions is the presence of kcat in Km’s numerator. Thus, whether Km is equal to Kd depends only on the relative size of k-1 and kcat. They are equal when k-1 is much larger than kcat. This condition provides a more precise way of thinking about when the rapid equilibrium assumption is valid: when ...
