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.
What happens to the reaction rate as the enzyme concentration is increased?
As enzyme concentration increases, the reaction rate usually increases because there are more enzyme molecules available to catalyze the reaction. This is because enzymes can bind to more substrate molecules simultaneously, leading to a greater frequency of successful collisions and faster conversion to product. However, once all substrate molecules are bound to enzymes (enzyme saturation), further increases in enzyme concentration will not significantly affect the reaction rate.
Is the enzyme cataylse the break down of a subtrate molecules?
Yes, the enzyme catalase catalyzes the breakdown of hydrogen peroxide into water and oxygen molecules. This reaction helps to protect cells from damage caused by reactive oxygen species.
What type of enzyme brings reactants closer together?
A ligase enzyme catalyzes the joining of two molecules by forming a chemical bond. This enzyme brings reactants closer together to facilitate the formation of the bond.
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 enzyme is responsible for cutting DNA molecules?
The enzyme responsible for cutting DNA molecules is called a restriction enzyme.
IS FAT A HORMONE OR ENZYME?
No it is not a hormone or an enzyme. It is a type of molecules

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.
The number of molecules with which an enzyme reacts is the?
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.
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.
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.
What does the enzyme ATPsynthetatse do?
ATPynthetatse is an enzyme that rejoins phosphates back to the adenosine in ATP molecules.
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 chemical can break up large molecules?
Enzyme
