The number of molecules with which an enzyme reacts is the?
turnover number
How do you calculate turnover number for an enzyme?
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.
What is the enzyme ADA?
Adenosine deaminase is an enzyme(EC3.5.4.4) involved in purine metabolism. It is needed for thebreakdown of adenosinefrom food and for the turnover of nucleic acidsin tissues.
How long would it take 1 picomole of enzyme to convert 1 micromole of the substrate to product if the turnover number was 1 per millisecond?
Depends on enzyme purity, activity and incubation conditions.
Define total enzyme concentration?
The optimum pH and optimum temperatures of an enzyme are simply levels that the enzyme work most effectively at. These levels contribute to factors such as the enzyme's protein structure. Different levels of pH and temperature can alter the integrity of the protein, this process is called denaturation. When an enzyme undergoes denaturation, its level of activity is inhibited by failure of the substrate to effectively attach itself to the active site.

When a protein is denatured what will happen to the turnover number?
The turnover number refers to the enzyme activity during a biochemical process. When a protein is denatured it can no longer function and so the turnover number goes down.
How do you measure the turnover of enzyme?
You take out a ruler. & you measure it. That is the most sufficent way i have done this.

What is catalytic constant?
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)
What is Kcat?
Catalytic turnover constant. See the article on enzyme kinetics. http://en.wikipedia.org/wiki/Kcat
Which enzyme has maximum turnover rate?
Catalase, which can convert about 40 million H202 molecules to H20 & O2 in 1 Sec.

Depends on enzyme purity, activity and incubation conditions.
4 molecules of an enzyme and 60000 molecules of substrate are taken all substrate molecules are converted into products in 5 minutes calculate turnover number of enzyme?
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.
