To calculate the percent activity of an enzyme, you first need to determine its actual activity, typically measured as the amount of product formed or substrate consumed over a specific time period. Next, compare this value to the maximum or theoretical activity (often defined under optimal conditions). The formula for percent activity is:
[ \text{Percent Activity} = \left( \frac{\text{Actual Activity}}{\text{Maximum Activity}} \right) \times 100 ]
This will give you the enzyme's performance as a percentage relative to its highest potential activity.
An enzyme's activity can appear to exceed 100% due to a cascade effect where the enzyme catalyzes multiple cycles of a reaction, leading to a cumulative amplification of the reaction. However, it is important to note that enzyme activity is typically expressed as a rate, which is a measure of the amount of substrate converted per unit time, and therefore cannot be greater than 100%.
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.
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.
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.
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.
Enrichment=specific activity of fraction/original specific activity of original sample
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.
To calculate Vmax and Km for enzyme activity data, you can use the Michaelis-Menten equation. Vmax is the maximum reaction rate of the enzyme, and Km is the substrate concentration at which the reaction rate is half of Vmax. By plotting a Lineweaver-Burk plot or a double reciprocal plot of the enzyme activity data, you can determine Vmax and Km by analyzing the slope and intercept of the line.

Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive

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.
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.
