What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.
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.
How many of the glycolysis enzyme molecules does a cell have?
It has 2 ATP molecules.
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 enzyme builds mRNA molecules bases on the code in DNA?
The enzyme is RNA polymerase.
Why does increase enzymes concentration promote enzyme activity?
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
What is the significance of the parameter kcat in enzyme kinetics?
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.
Differentiate extra and intracellular enzymes?
An extracellular enzyme is one which reacts outside of the cell. An intracellular enzyme is one which reacts inside of the cell.
What enzyme is responsible for cutting DNA molecules?
The enzyme responsible for cutting DNA molecules is called a restriction enzyme.
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)
How many substrate molecules does a typical enzyme act on per second?
A single enzyme molecule can act on about 1000 substrate molecules per second.
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.
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.
IS FAT A HORMONE OR ENZYME?
No it is not a hormone or an enzyme. It is a type of molecules

What factors affect enzyme activity?
Temperature - too cold the enzyme will still work but slowly, too hot and the enzyme will become denatured . As temperature increases, the kinetic energy of the molecules increases so they move around more, meaning that there are more collisions between the enzymes and substrate molecules and therefore more reactions. pH - different types of enzymes work best in different pH environments. A change in pH interferes with the shape of the enzymes active site (where it bonds and reacts with substrate) and therefore does not fit the shape of the substrate as well so the enzyme is unable to work on the substrate. enzyme and substrate concentration - how many there is of each. Changing the concentrations of enzyme and substrate concentrations will affect the number of collisions between them and therefore the number of reactions. enzyme inhibitors - these are molecules which bind to enzymes, reducing their activity (many drugs are enzyme inhibitors). co-factors - these are chemical compounds which bind to enzymes and which are needed by the enzyme to work on substrate molecules. They are often called helper molecules.
What is the Difference between intracellular enzyme and extracellular enzyme?
Intracellular enzymes are enzymes that function inside the cell, where they participate in various metabolic reactions. Extracellular enzymes, on the other hand, are enzymes that are secreted outside the cell to catalyze reactions in the extracellular environment, such as breaking down larger molecules into smaller ones for nutrient absorption.
