An uncompetitive inhibitor interacts with the enzyme•substrate complex to form a ternary complex (ES•I). This equilibrium reaction can be described as follows: ES + I ⇌ ESI Modify the simplified kinetic scheme you drew for E + S ⇌ E + P to include this equilibrium expression
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

expression
Enzyme inhibition is a process by which the activity of an enzyme is altered. Inhibitors are substances that decreases the catalytic activity of an enzyme by altering the interaction between the enzyme & substrate.
Enzyme inhibition can be classified into the following types:
- Reversible
- Irreversible
The reversible enzyme inhibition can be categorized into the following types:
- Competitive
- Non-Competitive
- Uncompetitive
Km indicates the Michaelis constant & Vmax (Vm) refers to the maximum velocity attained by the reaction. E refers to the Enzyme, S refers to the substrate, P refers to the product & I refer to the inhibitor.
