Here's a precise problem for a chemistry student to solve related to enzyme kinetics and inhibition:A researcher wants to determine the Km and Vmax values of an enzyme that catalyzes the conversion of substrate A to product B. They measure the initial reaction rates at varying substrate concentrations and obtain the following data:| [A] (mM) | Initial Reaction Rate (μmol/min) ||----------|---------------------------------|| 1.0 | 0.10 || 2.5 | 0.20 || 5.0 | 0.28 || 10.0 | 0.32 || 20.0 | 0.35
