In a model of enzyme action, the enzyme can attach only to a substrate (reactant) with a specific shape. The enzyme then changes and reduces the activation energy of the reaction so reactants can become products. The enzyme is unchanged and is available to be used again.

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 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.


Can the presence of inhibitors or activitors affect enzyme activity?

Yes, inhibitors can decrease enzyme activity by binding to the enzyme and preventing substrate binding. Activators can increase enzyme activity by binding to the enzyme and enhancing substrate binding or catalytic activity. Both inhibitors and activators can modulate enzyme activity by changing the enzyme's structure or function.


What can change the way an enzyme acts?

Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.


What determine an enzymes activity?

There are several things that determine an enzyme's activity. The main determinants include the structure of the enzyme, temperature, pH and so much more.

inhibitor


How does the allosteric enzyme curve illustrate the relationship between enzyme activity and the binding of regulatory molecules?

The allosteric enzyme curve shows how enzyme activity changes when regulatory molecules bind to the enzyme. This curve demonstrates that the binding of regulatory molecules can either increase or decrease enzyme activity, depending on the specific enzyme and regulatory molecule involved.


Why is protein concentration necessary for accurate comparison of the enzyme activity of the fractions?

Enzyme activity sometimes reflects the amount of protein expressed in a cell--however, due to enzyme inhibitors, the enzyme activity is not always reflective of the amount of protein expressed by a cell.

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.


How do you calculate specific activity of salivary amylase?

Specific activity of salivary amylase can be calculated by dividing the total enzyme activity (in units) by the total protein concentration (in mg). The formula is: Specific activity = Total enzyme activity (units) / Total protein concentration (mg). This calculation gives a measure of the enzyme's activity per unit of protein.
