What does Michaelis-Menten equation calculate?

The Michaelis-Menten equation calculator allows you to discover the kinetics of one-substrate reaction catalyzed with an enzyme. Michaelis-Menten kinetics allows you to calculate the rate of the reaction, V, substrate concentration, Km, and the maximum rate of reaction, Vmax.

What is Michaelis-Menten equation and its applications?

The model takes the form of an equation describing the rate of enzymatic reactions, by relating reaction rate (rate of formation of product, ) to , the concentration of a substrate S. Its formula is given by. This equation is called the Michaelis–Menten equation.

How do you calculate Km and Vmax?

From the graph find the maximum velocity and half it i.e. Vmax/2. Draw a horizontal line from this point till you find the point on the graph that corresponds to it and read off the substrate concentration at that point. This will give the value of Km.

Which of the following is true when Michaelis-Menten equation is applied?

Which of the following is true about Michaelis-Menten kinetics? Explanation: Km is defined as the concentration of substrate at which enzyme is working at half of maximum velocity. Explanation: At low substrate concentration, the rate of a reaction is determined by the rate of formation of an enzyme-substrate complex.

What is the formula for calculating Vmax?

Ease of Calculating the Vmax in Lineweaver-Burk Plot Next, you will obtain the rate of enzyme activity as 1/Vo = Km/Vmax (1/[S]) + 1/Vmax, where Vo is the initial rate, Km is the dissociation constant between the substrate and the enzyme, Vmax is the maximum rate, and S is the concentration of the substrate.

How do you plot Michaelis-Menten?

Plotting the Michaelis-Menten Curve Label the x-axis mM of [S] or concentration of substrate. Label the y ax- sec/micro-mole of V or velocity of reaction. Insert different values of [S] into the Michaelis-Menten equation, along with the values found for Km and Vmax, to solve for V.

What are the limitations of Michaelis-Menten equation?

When there is a substrate inhibition or activation due to the binding of a second substrate molecule, the Michaelis–Menten equation does not hold. The steady-state and rapid equilibrium kinetics do not give detailed information on the existence of multiple intermediates or on their lifetimes.

What are the units of Vmax and Km?

Vmax is a rate of reaction. It will have units of: or or etc. min sec min Vmax depends on the structure the enzyme itself and the concentration of enzyme present. KM is a the concentration substrate required to approach the maximum reaction velocity – if [S]>>Km then Vo will be close to Vmax.

How do you plot Michaelis Menten?

What is km unit?

Kilometre (km), also spelled kilometer, unit of length equal to 1,000 metres and the equivalent of 0.6214 mile (see metric system).
