No change in enzyme activity would be observed.
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.
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.
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 noncompetitive inhibitor has a structure that does not resemble the substrate structure. A compound that binds to the surface of an enzyme, and changes its shape so that a substrate cannot enter the active site is called a noncompetitive inhibitor.

Add more substrate; it will outcompete the inhibitor and increase the reaction rate. Competitive inhibition can be overcome by adding more substrate to outcompete the inhibitor. Many drugs used to treat different medical conditions, including hypertension, are competitive inhibitors. It is fairly easy to make a molecule that is similar in structure to a particular substrate because the known enzyme's shape can be used as a model of what the molecule needs to look like. It is more difficult to make a noncompetitive inhibitor because it is less obvious what the noncompetitive inhibitor's shape and structure should be.

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
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.

Of course. That is the meaning of ' noncompetitive inhibitor. ' It does not compete with the substrate at the active site but inhibits enzyme activity at the allosteric ( other site ) site.

The higher the substrate concentration, the higher the rate of reaction, up till the point when the limiting factor is no longer the concentration of substrate but other factors like enzyme concentration of temperature.
