If two enzymes (e.g.,pyruvate dehydrogenase and pyruvate carboxylase)compete for the same substrate (pyruvate),the one with the higher Km has less affinity and will be more active when pyruvate concentrations are high.

Question

Quizplus · Accepted Answer

The Km value of an enzyme is inversely related to its affinity for its substrate; thus, an enzyme with a higher Km has a lower affinity for its substrate and will be more active at higher substrate concentrations, as it requires more substrate to reach its half-maximal activity.

If Two Enzymes (E
