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 ...
