Allosteric Inhibition

Allosteric inhibition is a type of enzyme regulation where an inhibitor binds to an enzyme at a site other than the active site, called the allosteric site. This binding induces a conformational change in the enzyme that alters its activity, typically reducing its ability to bind to the substrate or catalyze the reaction. Allosteric inhibition … Read more

Uncompetitive Inhibition

Uncompetitive inhibition is a type of enzyme inhibition where the inhibitor binds only to the enzyme-substrate complex, not to the free enzyme. This binding occurs at a site other than the active site, typically called the allosteric site, and the binding of the inhibitor reduces the enzyme’s ability to convert the substrate into a product. … Read more

Non-Competitive Inhibition

Non-competitive inhibition is a form of enzyme inhibition where the inhibitor binds to a site on the enzyme other than the active site, called the allosteric site. This binding changes the enzyme’s shape, which reduces its ability to catalyze the reaction, even though the substrate can still bind to the enzyme. Key Features of Non-Competitive … Read more

Competitive Inhibition

Competitive inhibition occurs when an inhibitor molecule competes with the substrate for binding to the enzyme’s active site. This form of inhibition is characterized by the fact that the inhibitor and the substrate cannot bind to the enzyme at the same time, as they share the same binding site. Key Features of Competitive Inhibition: Mechanism: … Read more

Enzyme Inhibition:

Enzyme inhibition refers to the process by which a molecule (an inhibitor) decreases the activity of an enzyme, preventing it from catalyzing a reaction efficiently. Inhibitors can interact with enzymes in several ways, and the type of inhibition depends on how the inhibitor binds to the enzyme and affects its activity. Types of Enzyme Inhibition: … Read more

Lineweaver-Burk Plot

The Lineweaver-Burk plot is a graphical representation of the Michaelis-Menten equation that helps to analyze enzyme kinetics and determine important parameters, such as the Michaelis constant (Km_mm​) and the maximum reaction velocity (Vmax_\text{max}max​). It is a double reciprocal plot, where the reciprocal of the reaction rate (1/v) is plotted against the reciprocal of the substrate … Read more

Enzyme Concentration

Enzyme concentration refers to the amount of enzyme available in a reaction mixture. It directly impacts the rate of an enzymatic reaction because enzymes are biological catalysts that speed up reactions by lowering the activation energy. Key Concepts: Effect of Enzyme Concentration on Reaction Rate: Direct Relationship: At a constant substrate concentration, increasing enzyme concentration … Read more

Substrate Concentration

Substrate concentration refers to the amount of substrate (reactant) available in a given volume of a reaction mixture. It plays a crucial role in biochemical and enzymatic reactions, where substrates interact with enzymes to form products. Key Concepts: Enzyme-Substrate Interaction: Enzymes are biological catalysts that bind to specific substrates. The substrate concentration influences the rate … Read more

pH

pH is a scale used to measure the acidity or basicity (alkalinity) of an aqueous solution. It ranges from 0 to 14 and is calculated based on the concentration of hydrogen ions (H+\text{H}^+H+) in the solution. Here’s what the pH scale means: pH < 7: The solution is acidic (higher concentration of H+\text{H}^+H+ ions). pH … Read more
