In uncompetitive inhibition, both the Km (Michaelis constant) and Vmax (maximum reaction rate) values decrease.
In uncompetitive inhibition, the inhibitor binds to the enzyme-substrate complex, not the free enzyme. This type of inhibition does not affect the Michaelis constant (Km) but decreases the maximum reaction rate (Vmax) of the enzyme.
Uncompetitive inhibition occurs when the inhibitor binds only to the enzyme-substrate complex, while non-competitive inhibition happens when the inhibitor binds to both the enzyme and the enzyme-substrate complex. Uncompetitive inhibition decreases the maximum reaction rate, while non-competitive inhibition reduces the enzyme's ability to bind to the substrate.
Uncompetitive inhibition leads to a decrease in the Michaelis constant (Km) because it binds to the enzyme-substrate complex, preventing the release of the product. This results in a slower rate of reaction and a lower Km value, indicating higher affinity between the enzyme and substrate.
Non-competitive inhibition occurs when an inhibitor binds to an enzyme at a site other than the active site, changing the enzyme's shape and reducing its activity. Allosteric inhibition involves an inhibitor binding to a specific regulatory site on the enzyme, causing a conformational change that decreases enzyme activity. The key difference is that non-competitive inhibition does not compete with the substrate for the active site, while allosteric inhibition involves binding to a separate site on the enzyme.
Allosteric inhibition occurs when a molecule binds to a site on an enzyme that is not the active site, causing a change in the enzyme's shape and reducing its activity. Competitive inhibition, on the other hand, happens when a molecule competes with the substrate for the active site of the enzyme, blocking the substrate from binding and inhibiting the enzyme's function.

I believe non competitive antagonists bind to an allosteric site that prevents the enzyme from binding substrate whereas uncompetitive binds and stabilizes the ES complex which slows down the reaction.
In chemical reactions, kinetics refers to the speed at which a reaction occurs, while equilibrium is the point where the rates of the forward and reverse reactions are equal. Kinetics determines how quickly a reaction reaches equilibrium, and equilibrium represents a balance between the forward and reverse reactions.
In a mixed inhibition scenario, as the concentration of the inhibitor increases, the Lineweaver-Burk (LB) plot takes on a distinctive pattern. Unlike uncompetitive or competitive inhibition, mixed inhibition involves the inhibitor binding to both the enzyme-substrate complex and the free enzyme, affecting the reaction kinetics. As the inhibitor concentration rises, the LB plot displays converging lines, indicating that the apparent affinity of the enzyme for the substrate diminishes. This convergence suggests that the inhibitor alters both the enzyme's active form and its substrate-bound configuration. The LB plot, in this context, serves as a visual representation of how the inhibitor impacts the enzyme's catalytic activity, offering insights into the complex interplay between substrates, enzymes, and inhibitors at varying concentrations.
To determine the rate constant k from a graph of reaction kinetics, you can use the slope of the line in a first-order reaction or the y-intercept in a second-order reaction. The rate constant k is typically calculated by analyzing the linear relationship between concentration and time in the reaction.
Inhibition percentage is calculated based on the difference between the control (no inhibitor) and the test (with inhibitor) activity. In a low concentration, even a small decrease in activity can lead to a high percentage inhibition compared to a high concentration where a larger decrease is needed to achieve the same percentage inhibition.

In the context of chemical reactions, dynamics refers to the study of the speed and pathways of reactions, while kinetics focuses on the factors that influence the rate of a reaction. Dynamics looks at how molecules move and interact during a reaction, while kinetics examines the factors that affect how quickly a reaction occurs.
