The active site.
substrate
D. substrate (a specific reactant acted upon by an enzyme is called the enzyme's substrate.)
If the reactant is affected by an enzyme, it then referred to as a SUBSTRATE.
substrates
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.
Enzyme increase the rate of reaction by decreasing its activation energy. Physically they provide the surface for the reactant to react now as the reactant have to attach on enzyme surface then it is to be ensure that the enzyme should have affinity or its surface should be like that it only fix the specific reactant in it so that only that reactant proceed the reaction. It just work like lock and key mechanism as only specific key can be fit in its lock to save the product individuality in same way enzymes are specific for their substrate so as to maintain the individulatiy of reaciton and product.
the region where a reactant binds to an enzyme is known as the active site
The site on the surface of an enzyme where a reactant binds is called the active site. This is where the chemical reaction takes place between the enzyme and its substrate. The active site has a specific shape that allows it to bind with the substrate molecule.
The reactant for the enzyme aspartase is aspartic acid. It catalyzes the conversion of aspartic acid into fumaric acid.
Generally in an enzyme-catalyzed reaction, the reactant is called the substrate, which in association with the enzyme forms the product.
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.
