In an enzyme catalyzed reaction what is the reactant called?
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
A reaction that is catalyzed by an enzyme usually absorbs less energy and is faster than normal reactions?
Reaction B
What reaction does the enzyme hexokinase catalyze?
First step of glycolysis- the phosphorylation of glucose to glucose-6-phosphate.
Why NaOH is used as stop solution to determine specific activity of alkaline phosphatase?
This serves two functions; first, it stops the enzyme-catalyzed reaction by changing the pH to one unsuitable for the enzyme (the enzyme is denatured at high pH and so unable to function). Second, it deprotonates the p-nitrophenol to give the yellow colored p-nitrophenylate.
What does it mean if enzymes are organic catalyst?
Enzymes are organic catalysts. A catalyst is a chemical that controls the rate of a reaction, but is itself not used up in the process. Reactions that are accelerated due to the presence of enzymes are known as enzyme-catalyzed reactions.
Rank reactions from fastest to lowest uncatalyzed reaction reaction catalyzed by enzyme A reaction catalyzed by enzyme B?
A reaction catalyzed by enzyme a reaction cataly by enzyme b uncatalyzed reaction
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
Name of reactants of an enzyme catalyzed reaction?
Polysaccharide
In a enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
catalyzed reaction
What are Enzyme-catalyzed reaction?
reactions in which enzymes are involved as catalysts.
In an enzyme catalyzed reaction what is the reactant called?
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
What has no effect on the rate of an enzyme-catalyzed reaction?
When an enzyme is saturated the amount of substrate added no longer as an effect on the rate of the reaction.
Describe the relationship between substrate concentration and the initial reaction rate of an enzyme-catalyzed reaction Is this a linear relationship What happens to the initial reaction rate as sub?
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
The reactants of an enzyme-catalyzed reaction are know as?
They are generally known as substrates.
What things can change the rate of an enzyme catalyzed reaction?
ur face
What enzyme catalyzes the reaction that creates creatine phosphate?
The reaction of creatine phosphate with ADP is catalyzed by the enzyme creatine kinase and is reversible.
Describe the roles of a catalyst and substrate in a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction's activation energy.A substrate is a reactant of an enzyme-catalyzed reaction.
