Does the allosteric effect in an enzyme change the enzyme's function?
Yes, the allosteric effect can change an enzyme's function by altering its activity or affinity for its substrate. This modulation is often achieved by a molecule binding to a site on the enzyme other than the active site, causing a conformational change that affects the enzyme's catalytic activity.
What is the effect of excess heat or temperature on an enzyme-?
With a lot of heat, the enzyme will be denatured meaning it will lose its shape and therefore its function.
In an allosteric enzyme the homotropic effect is seen when?
In an allosteric enzyme, the homotropic effect occurs when the substrate acts as a ligand and binds to the active site, influencing the enzyme's activity. This binding can either enhance or inhibit the enzyme's function, depending on the specific enzyme and substrate involved.
What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
What has no effect on the rate of an enzyme-catalyzed reaction?
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.

What is the effect of excess heat or temperature on an enzyeme?
Excess heat or temperature can denature an enzyme, altering its shape and disrupting its active site. This can result in loss of enzyme function and decreased catalytic activity. Ultimately, high temperatures can render the enzyme nonfunctional.
Factor that effect enzyme function?
Factors that can affect enzyme function include temperature, pH levels, substrate concentration, enzyme concentration, and the presence of inhibitors or activators. Changes in any of these factors can alter the activity of enzymes and either increase or decrease their ability to catalyze reactions.
What is the active site for an enzyme?
The place where the substrate and the enzyme meet to allow the enzyme to function.
What does enzymes functions depend on?
The function of an enzyme is dependent on the shape of the enzyme. The structure and shape determines what the enzyme can do.
Why does denaturing effect enzyme reactions?
If you denature an enzyme, you do not kill it because it was never alive, but you shut it down. It cannot work any longer and therefore it cannot speed up the reaction. The overall reaction will be slower because there are less enzymes.
What has no effect on the rate of an enzyme-catalyzed reaction?
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
Enzyme activators like cofactors or substrates can switch on enzyme activity by binding to the enzyme and promoting its function. Conversely, inhibitors can switch off or reduce enzyme activity by binding to the enzyme and preventing its normal function.
What happens to an enzyme when it is heated?
When an enzyme is heated it is denatured, which means that it can no longer function.
What is part of an enzyme's usual derived from?
Usually an enzyme is named after it's function.
