Enzyme-substrate specificity means that a substrate can fit into an enzyme similar to a key fitting into a lock. The active site of the enzyme is what determines its specificity. An enzyme can hence catalyze a reaction with a specific substrate, such as amylase catalyzing starch molecules. During these reactions, the substrate is held in a precise optimum position to create and break bonds, catalyzing the molecule.

∙ 9y agoEach enzyme has one unique chemical reaction to catalyze - the substrates are the molecules being acted upon by the enzyme, while the molecules resulting from the catalyzed reaction are called the products. The enzyme remains unaltered.

According to American Heritage Dictionary a substrate is - # The material or substance on which an enzyme acts. # Biology A surface on which an organism grows or is attached. # An underlying layer; a substratum. # Linguistics An indigenous language that contributes features to the language of an invading people who impose their language on the indigenous population.

What is a induced fit hypothesis?
a. The substrate can be altered so it is induced to fit into the enzyme's active site. b. The enzyme changes its shape slightly as it binds to the substrate. c. The enzyme is altered so it is induced to fit many different types of substrate. d. Several sites on an enzyme can be induced to act on a substrate.
What is an active site and what is its relationship to an enzyme?
an active site in an enzyme is the area that breaks the bond in its substrate. E.g. a maltose molecule's glycocide bond is broken by the active site in a maltase enzyme.
What are the characteristics of an enzymatic reaction?
pH Temperature Ionic Strength Aw Substrate Concentration Substrate location.
Do substrates get consumed in enzyme reactions?
On active sites of enzymes, substrates bind to form products.Specific activity is usually expressed as μmol of substrate transformed to product per minute per milligram of enzyme under optimal conditions of measurement.The rate of a reaction is the concentration of substrate disappearing (or product produced) per unit time (mol-1 L-1 s-1 ).
Why must a molecule have a specific shape if it is to be a substrate of an enzyme?
Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.
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.
Why does it happen enzyme after it participates in a reaction?
After the enzyme has converted the substrate to the product, it is now free to accept more substrate. The enzyme does not get changed or altered in a reaction.
What is it called when and enzyme and substrate come together?
The binding of an enzyme and a substrate forms an enzyme-substrate complex. It lowers the activation energy of a chemical reaction
What affect does too much substrate have on the rate of an enzyme reaction?
The enzyme becomes saturated by the substrate and enzyme activity plateaus.
What simple experiment might you perform to test the hypothesis that an enzyme combines with its substrate when it acts?
in the absences of the enzyme the reaction is very slow,and at the end of the reaction enzyme is separated that shows substrate 1st bind to the enzyme
What happens to the enzyme after the substrate is changed?
enzyme works as a catalyst before and after the reaction it is preserved
The reactants of an enzyme-catalzyed reaction are known as what?
The substrate is the molecule affected by the enzyme.
What happens at the active site of an enzyme?
the substrate bonds to the enzyme at the active site
What is the place where the substrate attaches to the enzyme?
The active site of an enzyme is the site where substrates undergo the reaction specfic to that enzyme.
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.
What does Active Site mean?
The active site on an enzyme is the place where the enzyme binds the substrate and the chemical reaction takes place that changes the substrate(s) into the products of the reaction.
What happens after a substrate binds to an enzyme?
Substrate a reactant molecule that binds to an enzyme. It has a specific shape that is complementary in shape to the active site of the enzyme. Product the substance or substances produced by the reaction between the enzyme and substrate.
