What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.
What are the four factors that effect enzyme activity?
The four factors that affect enzyme activity are temperature, pH, substrate concentration, and the presence of inhibitors or activators. Temperature and pH can alter the enzyme's shape, while substrate concentration determines the rate of reaction. Inhibitors and activators can either decrease or increase enzyme activity, respectively.
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Increasing the substrate concentration will not decrease the effect of a noncompetitive inhibitor because a noncompetitive inhibitor binds to an allosteric site on the enzyme, which is different from the active site where the substrate binds. Therefore, increasing the substrate concentration does not compete with the noncompetitive inhibitor for binding.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What can effect how the enzyme and substrate come together?
Factors such as temperature, pH, substrate concentration, and the presence of inhibitors or activators can affect how enzymes and substrates come together. Changes in these factors can alter the shape and activity of enzymes, impacting their ability to bind with substrates and catalyze reactions.

What cause competition?
It slows down or even stop the enzymatic activity because it compete the actove site of the enzymes with substrate and its effect can be reduced by concentrating the concentration of substrate or add more subatrate therefore more substrate are compete with the inibitors
What three conditions can effect enzyme reactions?
pH level: Enzymes have an optimal pH at which they function, and deviating from this pH can affect their activity. Temperature: Enzymes can denature if exposed to extreme temperatures, reducing their effectiveness. Substrate concentration: Enzyme activity can be influenced by the amount of substrate available for the reaction.
How does changing the substrate concentration exhibit the same effect as changing the enzyme concentration?
For the enzyme to work, its particles must collide with the particles of the substrate. The more particles there are per unit volume, the more frequent the collisions will be. Thus changing the concentration of either chemical will have the same effect.
Why will increasing the substrate concentration not decrease the effect of a non competitive inhibitor?
Increasing the substrate concentration will not decrease the effect of a noncompetitive inhibitor because a noncompetitive inhibitor binds to an allosteric site on the enzyme, which is different from the active site where the substrate binds. Therefore, increasing the substrate concentration does not compete with the noncompetitive inhibitor for binding.
What is the Effect of dilution on enzyme activity?
At a high ion concentration, the ion interfere with the bonds between the side groups of the amino acids making up the enzyme (which is a protein). This causes the enzyme to lose its shape, called denaturation. If the enzyme loses its shape, it can no longer accept and react substrate, so the rate of enzyme activity decreases.

temperature,pH and substrate concentration

Increasing the substrate concentration in an enzymatic reaction could overcome what?
Increasing the substrate concentration in an enzymatic reaction could overcome low reaction rates due to insufficient substrate molecules available for the enzyme to bind to, thereby accelerating the reaction rate. This is known as the substrate concentration effect, where higher substrate concentrations can lead to higher reaction rates until the enzyme becomes saturated.
The effect of substrate concentration on the rate of reaction of h202 and catalase?
As substrate concentration increases, the rate of reaction between hydrogen peroxide (H2O2) and catalase also increases initially due to more substrate molecules colliding with enzyme active sites. However, at a certain point, the rate of reaction plateaus as all enzyme active sites become saturated and adding more substrate does not increase the reaction rate further. This is known as the enzyme substrate saturation point.
How do you change the concentration of the substrate where the substrate is milk and the enzyme is renin?
You can change the concentration of the substrate (milk) by diluting or concentrating it before adding the enzyme renin. Dilution will decrease the substrate concentration, while concentration will increase it. Make sure to measure accurately for consistent results.
