Because of the unique three-dimensional shape of the active site
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
The term used for all molecules on which an enzyme acts is "substrate." Substrates bind to the enzyme's active site, where the enzyme catalyzes a biochemical reaction, transforming the substrate into products. Each enzyme is specific to its substrate, allowing for precise regulation of metabolic pathways.
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
Enzymes are proteins, which are made up of amino acids. Each enzyme has a different sequence of amino acids and changing even one amino acid will mean that the tertiary structure of the enzyme will be lost and so will it's active site. As enzymes are substrate specific, only a certain substrate will bind to its active site, due to its amino acid sequence determining the shape of the active site.
substrate
An enzyme's active site is a groove or dip in the enzyme that is shaped for a particular substrate to attach to.
enzyme-substrate complex
in an enzyme-substrate complex, the enzyme acts on the substrate .
All enzyme's are catalysts for certain chemical reactions. Each enzyme will only work with a certain substrate one analogy being that the enzyme is a key and the substrate is a keyhole, and each enzyme has a unique enzyme.
Enzymes are proteins that have a very specific structure. The region on the surface of an enzyme that is responsible for binding and converting the subtract into the product is called the active site.
When an enzyme and substrate come together, it is called the enzyme-substrate complex. This complex is a temporary intermediate state in which the enzyme binds to the substrate to catalyze a chemical reaction.
The substrates are converted into products, which are released.
A substrate is the substance acted upon by an enzyme. The enzyme substrate complex is when an enzyme molecule combines with its substrates.
The term used for all molecules on which an enzyme acts is "substrate." Substrates bind to the enzyme's active site, where the enzyme catalyzes a biochemical reaction, transforming the substrate into products. Each enzyme is specific to its substrate, allowing for precise regulation of metabolic pathways.
When a substrate fits into the active site of an enzyme, an enzyme-substrate complex is formed. This complex allows for the enzyme to catalyze a specific chemical reaction on the substrate.
substrate can fit into, due to complementary shapes and charges. This allows the enzyme to specifically catalyze a particular reaction. Any changes to the active site can impact the enzyme's ability to bind to its substrate and perform its function.
