What else can I help you with?
What is an aspartase?
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
What is true of substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
Do enzymes form a permanent or temporary association with a reactant?
Enzymes form a temporary association with a reactant, known as a substrate, to facilitate a chemical reaction. This association allows the enzyme to catalyze the reaction without being permanently altered or consumed in the process.
Why is it important that enzymes are not changed by the reaction that they control?
Enzymes need to remain unchanged by the reaction they catalyze in order to be reused multiple times, ensuring efficiency in the cell. If enzymes were changed during the reaction, they would not be available to catalyze subsequent reactions, which would slow down essential cellular processes.
What would happen if a reactant molecule with a different shape to the enzyme came into contact with the enzymes active site?
If a reactant molecule with a different shape than the enzyme comes into contact with the enzyme's active site, it is unlikely to bind effectively. Enzymes have specific active sites that accommodate only particular substrates, a concept known as the "lock and key" model. If the shape does not fit, the molecule will not trigger the catalytic activity of the enzyme, and no reaction will occur. This specificity ensures that enzymes catalyze only the intended biochemical reactions.

Do Enzymes raise the activation energy to break the bonds of reactant molecules?
Yes
When talking about enzymes where do reactant molecules bind and convert chemically to a product?
Active site

What chemical reduces the amount of activation energy needed for a reaction but is not a reactant?
Enzymes catalyze certain reactions.
What is a true of a substrate?
It acts as a reactant. In a chemical reaction A substrate is a molecule that is reacted on by enzymes.
What is the reactant for the enzyme peptidase?
The reactant for the enzyme peptidase is a peptide molecule. Peptidase enzymes catalyze the breakdown of peptide bonds within peptides or proteins, resulting in the release of amino acids.
One particular reactant can only produce one type of product regardless of the enzymes true of false?
False. Enzymes can catalyze multiple reactions, converting one reactant into multiple products. The specificity of an enzyme depends on its active site, which is tailored to bind to specific substrates and facilitate specific chemical reactions.
When talking about enzymes where do reactant molecules bind and convert chemically product?
In enzymes, reactant molecules bind to a specific region called the active site. This is where the chemical reaction takes place and the reactants are converted into products. The active site has a specific shape that matches the reactants, allowing for precise binding and conversion.
What do enzymes to do a chemical reaction?
Enzymes are catalysts in a chemical reaction, they are used in chemistry to increase the speed of a specific chemical reaction. A single enzyme will not speed up multiple chemical reactions, usually it is limited to one reactant.
