Michaelis constant (km) of an enzyme is substrate concentration at which the reaction attains

Question

Michaelis constant (km) of an enzyme is substrate concentration at which the reaction attains (A) its maximum velocity (B) half its maximum velocity (C) double its maximum velocity (D) its normal velocity

Tardigrade Admin · Accepted Answer

: Michaelis constant (Km) is the concentration of substrate that permits an enzyme reaction rate to be half-maximal, or at which half of the substrate molecules are engaged with enzyme molecules.

Q. Michaelis constant (km) of an enzyme is substrate concentration at which the reaction attains

its maximum velocity

half its maximum velocity

double its maximum velocity

its normal velocity

: Michaelis constant $(K_{m})$ is the concentration of substrate that permits an enzyme reaction rate to be half-maximal, or at which half of the substrate molecules are engaged with enzyme molecules.
