Explain the Michaelis-Menten equation and its significance in enzyme kinetics.

The Michaelis-Menten equation describes the initial reaction velocity as a function of substrate concentration. It is significant in enzyme kinetics as it provides insights into the behavior of enzymes and their substrates, allowing for the determination of key parameters such as Vmax and KM.

What is the significance of KM in the Michaelis-Menten equation?

KM is the substrate concentration that yields half of the maximum reaction velocity (½ Vmax). It is a measure of the affinity of the enzyme for its substrate, providing valuable information about the enzyme-substrate interaction.

How is the Lineweaver-Burk equation derived from the Michaelis-Menten equation?

The Lineweaver-Burk equation is derived by taking the reciprocal of both sides of the Michaelis-Menten equation. This manipulation results in a linear equation that can be used to determine Vmax and KM.

Explain the linearization process in the Eadie-Scatchard plot.
