Kinetics Calculator

Results

Reaction Rate (v) 0.00 µmol/min

Data Source and Methodology

The calculations are based on foundational biochemical formulas such as the Michaelis-Menten equation, widely recognized in biochemical research.

All calculations are strictly based on the formulas and data provided by this source.

The Formula Explained

Michaelis-Menten Equation: \( v = \frac{{V_{max} \times [S]}}{{K_m + [S]}} \)

Glossary of Variables

  • [S]: Substrate concentration in millimolar (mM).
  • Vmax: Maximum reaction rate achievable by the system, expressed in µmol/min.
  • Km: Michaelis constant, a measure of the affinity of the enzyme for the substrate, expressed in mM.
  • v: Reaction rate, expressed in µmol/min.

How It Works: A Step-by-Step Example

Assume you have a substrate concentration of 5 mM, a Vmax of 100 µmol/min, and a Km of 10 mM. By substituting these values into the Michaelis-Menten equation, the reaction rate (v) can be calculated.

Using the formula: \( v = \frac{{100 \times 5}}{{10 + 5}} = \frac{500}{15} = 33.33 \text{ µmol/min} \)

Frequently Asked Questions (FAQ)

What is the Michaelis-Menten equation?

The Michaelis-Menten equation describes the rate of enzymatic reactions by relating reaction rate to substrate concentration.

How do I find the correct Vmax and Km?

Vmax and Km are determined experimentally by measuring reaction rates at various substrate concentrations and using nonlinear regression to fit the Michaelis-Menten equation to the data.

What conditions affect Km and Vmax?

Temperature, pH, and enzyme concentration can affect the values of Km and Vmax.

Can this calculator be used for all enzymes?

This calculator is applicable to enzymes that follow Michaelis-Menten kinetics, which is a common model for many but not all enzymes.

Why is understanding enzyme kinetics important?

Understanding enzyme kinetics is crucial for drug development, metabolic engineering, and understanding biological processes.
