What is the derivation of Michaelis-Menten equation?
The Michaelis-Menten equation arises from the general equation for an enzymatic reaction: E + S ↔ ES ↔ E + P, where E is the enzyme, S is the substrate, ES is the enzyme-substrate complex, and P is the product.
How do you explain Michaelis-Menten equation?
The Michaelis–Menten equation (Eqn (4)) is the rate equation for a one-substrate enzyme-catalyzed reaction. This equation relates the initial reaction rate (v0), the maximum reaction rate (Vmax), and the initial substrate concentration [S] through the Michaelis constant KM—a measure of the substrate-binding affinity.
What is the steady-state assumption equation?
The steady state assumption relies on the fact that both the formation of the intermediate from reactants and the formation of products from the intermediate have rates much higher than their corresponding reverse reactions. In other words, steady state assumes that k1>>k-1 and k2>>k-2.
What is steady-state kinetics?
Steady-state kinetics applies whenever the concentration of the substrate is well above that of the enzyme, so that the rate of change of substrate concentration greatly exceeds the rate of change of the concentration of any enzyme form.
What is the steady state kinetics?
What is steady-state in enzyme kinetics?
In steady-state kinetics, initial rates of reactions are measured in a regime in which each enzyme molecule binds substrate and catalyzes its conversion to product multiple times. Hence, steady-state kinetics is also frequently referred to as multiple-turnover kinetics.
How do you find Vmax and Km from Michaelis-Menten?
- V = Vmax [S]
- Michaelis-Menten Equation.
- KM + [S]

What is steady state reaction?
When a reaction involves one or more intermediates, the concentration of one of the intermediates remains constant at some stage of the reaction. Thus, the system has reached a steady-state.
What is steady-state principle?
In chemistry, a steady state is a situation in which all state variables are constant in spite of ongoing processes that strive to change them. For an entire system to be at steady state, i.e. for all state variables of a system to be constant, there must be a flow through the system (compare mass balance).
What is steady-state concept?
steady-state theory, in cosmology, a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
What is steady-state theory PDF?
The Steady State Theory states that although the universe is expanding, it does not change its look over time. For this to work, new matter must be formed to keep the density equal over time.
