Vedclass · Accepted Answer

Michaelis-Menten constant $(K_m)$

Vedclass · Answer

(B) The Michaelis-Menten constant,denoted as $K_m$,is defined as the substrate concentration at which the reaction rate is exactly half of the maximum velocity $(V_{max}/2)$.This constant is a measure of the affinity of the enzyme for its substrate.$A$ lower $K_m$ value indicates a higher affinity of the enzyme for the substrate.

At which substrate concentration does an enzyme exhibit half of its maximum velocity?
