Because you will still have the same number of enzymes inhibited. For example, you have 20 enzymes and 10 non-competitive inhibitors. Regardless of substrate concentration, at any one time, there will only be 10 enzymes available to accept a substrate. Increasing the substrate concentration does not affect this.
both substrate and competitive inhibitor
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
Competitive inhibition is where a inhibitor has a structural similarities of a substrate. Due this the inhibitor binds to the active site of the enzyme,where normally substrate binds. This binding of the inhibitor to the enzyme forms a EI complex instead of ES complex and thus inhibiting the catalytic activity of an enzyme. Non competitive inhibition is when inhibitor possessing same structure of substrate binds to the site other than the active site of an enzyme. The substrate binds to the active site of an enzyme. This binding of the inhibitor to the site other than an active site disturbs the normal structure of an enzyme. Thereby, lowering the catalytic activity of an enzyme.
A competitive inhibitor competes with the substrate to bind to the active site while a noncompetitive inhibitor binds to an allosteric site of the enzyme (one other than the active site). Thus no amount of substrate can overcome or in a sense interfere with the inhibitors binding to an allosteric site.
An enzyme can overcome the presence of a competitive inhibitor by increasing the substrate concentration The reaction rate falls direct propartional to the concentration fall (which is the result of that same reaction). This is called 'first order reaction rate'.
competitive inhibition
This would be a competitive inhibitor. It can be a structural analog of the substrate. This type of inhibition can be out competed by adding more substrate. A competitive inhibitor increases the Km of the enzyme.
Competitive inhibitor. It is termed to be an analogue. It is also known to sometimes act as a "catalytic poison".
The vmax stays the same as the competitive reversible inhibitor does not affect catalysis in the enzyme-substrate.

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.
