The enzymes ability to stretch reactants and move them towards a transition state
Competitive inhibitors compete with the substrate for the enzyme's active site, while noncompetitive inhibitors bind to a different site on the enzyme. Competitive inhibitors can be overcome by increasing substrate concentration, while noncompetitive inhibitors cannot. Both types of inhibitors reduce enzyme activity, but competitive inhibitors specifically affect the binding of the substrate, while noncompetitive inhibitors can alter the enzyme's shape or function.
Competitive inhibitors bind to the active site of the enzyme, competing with the substrate, while noncompetitive inhibitors bind to a site other than the active site, changing the enzyme's shape and preventing substrate binding. Competitive inhibitors can be overcome by increasing substrate concentration, while noncompetitive inhibitors cannot.
Competitive inhibitors bind to the active site of enzymes, blocking the substrate from binding and inhibiting the enzyme's activity.
I would just call it an inhibitor. An inhibitor may be a small molecule,such as a metal or it may be a protein.
Non-competitive inhibitors bind to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and preventing the substrate from binding effectively.

Competitive inhibitors can be overcome by increasing the substrate concentration since they bind to the active site of the enzyme, preventing substrate binding. By adding more substrate, the probability of substrate binding to the enzyme and outcompeting the inhibitor increases. This effectively reduces the impact of the competitive inhibitor on the enzyme's activity.

Yes, enzyme reactions can be slowed or halted using inhibitors. Inhibitors can bind to the enzyme and prevent it from binding to its substrate, thus inhibiting the reaction. There are different types of inhibitors, such as competitive inhibitors that compete with the substrate for binding to the enzyme, and non-competitive inhibitors that bind to a different site on the enzyme and alter its shape or function.
Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding. Noncompetitive inhibitors bind to a site other than the active site, changing the shape of the enzyme and preventing substrate binding. Uncompetitive inhibitors bind only to the enzyme-substrate complex, preventing catalysis.
Inhibitors are substances that alter the activity of enzymes by combining with them in a way that influence the binding of substrate and/or its turnover number. Many inhibitors are substances that structurally resemble their enzyme's substrate but either do not react or react very slowly compared to substrate.There are two kinds of inhibitors: a) competitive inhibitors (those compete directly with a normal substrate for an enzyme-binding site), and b) uncompetitive inhibitors (these bind directly to the enzyme-substrate complex but not to the free enzyme).
Competitive inhibitors decrease the maximum reaction rate (Vmax) of an enzyme by competing with the substrate for the enzyme's active site, which reduces the efficiency of the enzyme-substrate complex formation and slows down the rate of the reaction.
Non-competitive inhibitors bind to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and preventing the substrate from binding effectively.
AnswerWhat does inhibitor do to enzyme activity?They prevent the reactions from happening. Non-competative inhibitors alter the shape of the active site so that the substrate no longer fits, and competative inhibitors block the active site.
Competitive inhibitors reduce enzyme activity by binding (in competition with the enzyme's substrate) to the active site. These inhibitors may be reversible or irreversible. With reversible inhibitors, which may release the enzyme, concentrations much higher than the concentration of the substrate would be required to completely block enzyme activity, and even then one or two reactions may take place over long periods of time. With irreversible inhibitors, which permanently attach to the enzyme, enzyme activity could be completely blocked when the amount of inhibitor matches the amount of enzyme. Competitive inhibition reduces the enzymes ability to bind substrate (so it lowers the KM) but does not alter the maximum rate (very high substrate concentrations would out compete for enzyme binding).Other types of inhibitors work in other ways. Non-competitive inhibitors bind to the enzyme on a site other than the active site. These too may be reversible or irreversible. Binding does not compete with substrate, so concentrations to completely block enzyme activity do not have to be as high as reversible competitive inhibitors. Non-competitive inhibition reduces the apparent maximum rate for the enzyme.Uncompetitive inhibitors bind only when the substrate is also bound to the enzyme (they bind to the enzyme-substrate complex). Both the maximum rate and substrate binding affinities appear lower.
