Five K_M values are given for the binding of substrates to a particular enzyme. Which has the strongest affinity when k ₁ is greater than k₂? A) 150 mM B) 0.15 mM C) 150 $\mu$M D) 1.5 nM E) 15000 pM

Question

Quizplus · Accepted Answer

The strongest affinity for an enzyme is indicated by the lowest K_m value, as it requires the least amount of substrate to reach half of its maximum reaction velocity. Among the given options, 1.5 nM (D) is the lowest concentration, indicating the highest affinity.
