1. What is the Enzyme Conservation Law?

The Enzyme Conservation Law states that the total initial enzyme concentration equals the sum of free enzyme, enzyme-substrate complex, and enzyme-inhibitor complex concentrations. This fundamental principle is used in enzyme kinetics to account for all forms of enzyme present in a reaction system.

2. How Does the Calculator Work?

The calculator uses the enzyme conservation law formula:

\[ [E_{initial}] = (E + ES + EI) \]

Where:

\( [E_{initial}] \) — Initial enzyme concentration (mol/m³)
\( E \) — Free catalyst concentration (mol/m³)
\( ES \) — Enzyme-substrate complex concentration (mol/m³)
\( EI \) — Enzyme-inhibitor complex concentration (mol/m³)

Explanation: This equation ensures mass balance in enzymatic reactions by accounting for all possible forms the enzyme can take during the reaction process.

3. Importance of Initial Enzyme Concentration Calculation

Details: Accurate determination of initial enzyme concentration is crucial for enzyme kinetics studies, determining reaction rates, understanding inhibition mechanisms, and calculating kinetic parameters such as Km and Vmax.

4. Using the Calculator

Tips: Enter all concentration values in mol/m³. Ensure values are non-negative and represent concentrations measured under the same experimental conditions.

5. Frequently Asked Questions (FAQ)

Q1: Why is enzyme conservation important in kinetics?
A: It ensures mass balance and allows accurate calculation of kinetic parameters by accounting for all enzyme species present in the system.

Q2: What units should be used for concentration values?
A: While mol/m³ is used here, any consistent concentration unit can be used as long as all inputs use the same unit.

Q3: Does this law apply to all types of enzyme inhibition?
A: Yes, the enzyme conservation law applies to competitive, non-competitive, uncompetitive, and mixed inhibition types.

Q4: What if there are multiple inhibitors present?
A: The formula would need to be extended to include all enzyme-inhibitor complexes: [E_initial] = E + ES + EI₁ + EI₂ + ... + EI_n

Q5: How does temperature affect these calculations?
A: Temperature affects enzyme activity and binding constants, but the conservation law itself remains valid regardless of temperature conditions.
