What is the place where the substrate attaches to the enzyme?
The active site is where the substrate binds to the enzyme. It is a region on the enzyme where the chemical reaction takes place. The active site is specific to the substrate molecule, allowing for precise catalysis to occur.
What can affect the speed of the enzyme action?
Factors that can affect the speed of enzyme action include temperature, pH, substrate concentration, and presence of inhibitors or activators. Enzymes work optimally within a specific temperature and pH range, and their reaction rate can increase with increasing substrate concentration. Inhibitors can slow down enzyme activity, while activators can enhance it.
WHich action would most likely increase the rate of an enzyme-controlled reaction during an experiment?
Increasing the temperature or increasing the concentration of substrate would most likely increase the rate of an enzyme-controlled reaction during an experiment. This is because higher temperatures or substrate concentrations can speed up the rate of enzyme-substrate collisions, leading to more enzymatic reactions taking place.
What is lock and key model?
in order to explain the mechanism of enzymes action a German chemist Emil fischer,in 184,proposed the lock and key model.According to this model both the enzymes and the substrate possess specific complementary geometric shapes that fit exactly into one another.This model explain enzyme specificity.
How do noncompetitive and allosteric inhibitors differ in their mechanisms of action on enzymes?
Noncompetitive inhibitors bind to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and preventing substrate binding. Allosteric inhibitors bind to a different site on the enzyme, causing a conformational change that affects the active site's ability to bind substrate.
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
In an experiment of Pepsin and BAPNA is pepsin the substrate?
No, pepsin is not the substrate in the experiment with BAPNA. BAPNA is the synthetic substrate used in this experiment to test the activity of the enzyme pepsin by measuring the rate of substrate cleavage. Pepsin acts on BAPNA as the enzyme, not the substrate.
Who does the substrate work on enzyme action?
The substrate is the molecule on which the enzyme acts. It binds to the active site of the enzyme, leading to catalysis of the chemical reaction. The shape and chemical properties of the substrate are important in determining which enzyme can act on it.
What are three factors that affect the action of an enzyme?
pH . Temperature . Substrate's Concentration
Which type of control agent never speeds an enzyme's action?
Substrate analog
What is an action hero?
An action hero is the heroic figure in a fictional work containing action.
Is a substrate an enzyme?
No, a substrate is the molecule that the enzyme acts upon to catalyze a reaction. Enzymes are proteins that function as biological catalysts, helping to speed up chemical reactions by lowering the activation energy.
What is the part in which the conflict builds gradually in intensity?
Rising action
How does increasing substrate concentration affect the rate of enzyme action when the enzyme concentration remains constant?
It doesn't
How does increasing enzyme concentration affect the rate of enzyme action when substrate concentration remains constant?
It doesn't
What is the place where the substrate attaches to the enzyme?
The active site is where the substrate binds to the enzyme. It is a region on the enzyme where the chemical reaction takes place. The active site is specific to the substrate molecule, allowing for precise catalysis to occur.
Is gradually a action verb?
The word 'gradually' is not a verb; gradually is an adverb, a word that modifies a verb or an adjective, or even another adverb. Example:We gradually paid off the mortgage.His gradually more painful leg finally drove him to seek medical treatment.
