What is a non protein helper of an enzyme molecule called?
A non-protein helper of an enzyme molecule is called a cofactor or a coenzyme. These molecules assist in the enzyme's activity by aiding in the catalytic process. Examples include metal ions like zinc or magnesium, and organic molecules like NAD+ or coenzyme A.
How does noncompetitive inhibition differ from allosteric inhibition in terms of their mechanisms of action on enzyme activity?
Noncompetitive inhibition and allosteric inhibition both affect enzyme activity, but through different mechanisms. Noncompetitive inhibition binds to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and reducing its activity. Allosteric inhibition, on the other hand, binds to a different site on the enzyme called the allosteric site, which also causes a change in the enzyme's shape and reduces its activity.
Substances that plug up an enzyme's active site are?
called inhibitors. Inhibitors disrupt the enzyme's ability to bind with its substrate, hindering its catalytic activity.
What is a molecule occupying the active site of an enzyme so that there can be no normal enzyme-substrate complex formed called?
It is called a competitive inhibitor. Competitive inhibitors bind to the active site of an enzyme, preventing the substrate from binding and inhibiting the enzyme's activity. This type of inhibition can be overcome by increasing the substrate concentration.
What can you do to regain the activity of the enzyme?
To regain the activity of an enzyme, you can try adjusting the pH and temperature to the optimal conditions for that specific enzyme. You can also remove any inhibitors that may be present, such as heavy metals or competitive inhibitors. Additionally, you can try adding cofactors or coenzymes that may be necessary for the enzyme to function properly.
What is the Effect of mineral and vitamin deficiency on enzyme activity?
many vitamins and minerals play crucial roles in many metabolisms as coenzyme or cofactor. Deficiency of those lower the related-enzyme activity.
What are cofactors in cells and what are they derived from?
Cofactors are nonprotein additions that are needed for enzyme activity. Cofactors are derived from vitamins and minerals.
Destruction of the structure of an enzyme is called what?
The destruction of the structure of an enzyme is called denaturation. Denaturation can be caused by factors such as heat, pH changes, or chemicals, leading to loss of the enzyme's biological activity.
What are the effects of physical activity on enzyme activity?
Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
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 is a non protein helper of an enzyme molecule called?
A non-protein helper of an enzyme molecule is called a cofactor or a coenzyme. These molecules assist in the enzyme's activity by aiding in the catalytic process. Examples include metal ions like zinc or magnesium, and organic molecules like NAD+ or coenzyme A.
An enzyme whose activity is affected when a molecule binds to a certain site other than the active site is called?
an allosteric enzyme
What is the loss of structure of an enzyme due to the increase in temperature called?
The loss of structure of an enzyme due to increased temperature is called denaturation. This process disrupts the enzyme's active site, leading to a loss of its biological activity and function.
How does noncompetitive inhibition differ from allosteric inhibition in terms of their mechanisms of action on enzyme activity?
Noncompetitive inhibition and allosteric inhibition both affect enzyme activity, but through different mechanisms. Noncompetitive inhibition binds to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and reducing its activity. Allosteric inhibition, on the other hand, binds to a different site on the enzyme called the allosteric site, which also causes a change in the enzyme's shape and reduces its activity.
Which organic molecule is sometimes required for certain enzyme activity called?
coenzymes
What do activators and inhibitors help regulate?
Activators and inhibitors help regulate the activity of enzymes. Activators can enhance enzyme activity by binding to the enzyme, while inhibitors can decrease enzyme activity by binding to the enzyme and preventing it from functioning properly.
This essential substance increases the rate of a biochemical reaction?
the inorganic substance which increases the enzyme activity is called?
