Enzyme turnover is a replacement of new for 'old'.
As enzyme concentration increases the more active sites there are avalible, so the rate of reaction increases. therefore the turnover number increases.Hope it helped!TashaThe above it not true. The turn over number is Vmax/Et so if the enzyme concentration is doubled the velocity will also be doubled. Therefore the turn over number will remain constnat.
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
Depends on enzyme purity, activity and incubation conditions.
The number of molecules with which an enzyme reacts is typically one or more substrate molecules. Enzymes bind to their substrates at their active sites to catalyze chemical reactions. The number of substrate molecules that can interact with an enzyme at a given time depends on factors like enzyme concentration, substrate concentration, and the kinetics of the enzyme-substrate complex formation.
Protease is an enzyme that breaks down proteins into smaller peptides or amino acids. It plays a crucial role in digestion, as well as in various cellular processes that involve protein turnover and regulation.
Kcat is the catalytic efficiency of an enzyme, representing how many substrate molecules an enzyme can convert to product per unit time at a particular enzyme concentration. It is a measure of the enzyme's turnover rate.

When a protein is denatured, its turnover number may decrease because denaturation can disrupt the protein's active site, leading to a decrease in its catalytic activity. The turnover number is a measure of how efficiently an enzyme can catalyze a reaction, so if denaturation affects the enzyme's ability to function properly, the turnover number may be altered.
You take out a ruler. & you measure it. That is the most sufficent way i have done this.
Kcat : First-order rate constant (kcat) reflecting the turnover number of the enzyme, or the number of molecules of substrate converted to product per unit time, when the enzyme is working at maximum efficiency, which called also turnover number. Kcat = Vmax / [E]total (Letian) Kcat : First-order rate constant (kcat) reflecting the turnover number of the enzyme, or the number of molecules of substrate converted to product per unit time, when the enzyme is working at maximum efficiency, which called also turnover number. Kcat = Vmax / [E]total (Letian)
The parameter kcat in enzyme kinetics represents the turnover number, which is the rate at which an enzyme can convert substrate molecules into product molecules. It is a crucial factor in determining the efficiency of an enzyme and its catalytic activity.
Assuming that the turnover number is 5000 per second, which you did not specify, than the number of molecules that can be reached by the enzyme in 5 minutes is just this:5 minutes * 60 seconds/minute * 5000 turnover/second = 150,000 turnoversThis is because 1 turnover counts as one molecule reached by the enzyme.If instead the turnover number was 5000 per minute, then it would be:5 minutes * 5000 turnovers/minute = 25,000 turnovers.If it was 5000 per hour, then it would be:5 minutes * 1 hour/60 minutes * 5000 turnovers/hour = 416.7 turnovers.
Catalase, which can convert about 40 million H202 molecules to H20 & O2 in 1 Sec.
In enzyme catalysis, the kinetic constant kcat represents the turnover number, or the rate at which an enzyme can convert substrate into product. The Michaelis constant Km represents the substrate concentration at which the enzyme works at half of its maximum speed. The relationship between kcat and Km is important because it helps determine the efficiency of an enzyme. Generally, a lower Km value indicates a higher affinity of the enzyme for its substrate, while a higher kcat value indicates a faster turnover rate.
In enzyme kinetics, the turnover number (kcat) and the Michaelis constant (Km) are related in a way that affects the efficiency of an enzyme. The turnover number (kcat) represents the maximum number of substrate molecules that an enzyme can convert into product per unit time when the enzyme is fully saturated with substrate. The Michaelis constant (Km) is a measure of the affinity of an enzyme for its substrate, indicating how easily the enzyme can bind to the substrate. The relationship between kcat and Km is important because it determines the efficiency of an enzyme. Generally, a lower Km value indicates a higher affinity of the enzyme for its substrate, meaning that the enzyme can bind to the substrate more easily. On the other hand, a higher kcat value indicates a faster rate of catalysis, meaning that the enzyme can convert substrate into product more quickly. In summary, a lower Km and a higher kcat value are desirable in enzyme kinetics as they indicate a higher efficiency of the enzyme in converting substrate into product.
