An enzyme is specific to one and only one reaction.
So if we consider Enzyme A, which combines X and Y to make Z, that is the ONLY reaction it will catalyze.
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
Structure allows enzymes to maintain specificity. The level of specificity varies from enzyme to enzyme, with some exhibiting absolute specificity while others are less specific.
enzyme-substrate specificity means that only a certain enzyme can fit into a substrate. it is kind of like a key-lock specificity where only one key can fit into that lock
1) absolute specificity 2) Group specificity 3) Linkage specificity 4) Stereochemical specificity
The allosteric site is distinct from the active site, and does not affect the substrate specificity of the enzyme
an enzyme catalyst has greater substrate specificity
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.
each enzyme has a specific substrate to which it binds through a definite active site and any other enzyme can not bind to it
Enzyme specificity .
Because enzymes are specific and speed only one type of reaction.
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job.
No; enzymes have substrate specificity, which means the substrate has to be a specific shape for the enzyme to bind to it.
There is an enzyme explanation whose specificity states that an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. This is the lock and key explanation.Ê
Lactase. This is due to enzyme-substrate specificity. The active site of lactase fits lactose but not sucrose.
The enzyme's surface folds are complementary to the substrate's surface folds.
An enzyme is specific to one and only one reaction. So if we consider Enzyme A, which combines X and Y to make Z, that is the ONLY reaction it will catalyze.
The active site is where a substrate binds. Enzymes have very specific shapes as do their active sites. This means that only molecules with that certain shape can fit in the active site. This is called the lock-and-key theory of enzyme specificity.
The R groups of the amino acids in its active site
Enzymes are specifically designed to only bind to certain molecules. If a molecule comes into contact with an enzyme and it is not its specific substrate it will not bind and no reaction will occur
It's produced in the mouth & works on starch to break it down into shorter polysaccharides.
Substrate molecule can fit into it
They can't catalyse reactions. The specificity of the active site of the enzyme is crucial: without it, the enzyme won't fit with he desired substrate, hence there won't be any reaction. Losing this specificity is due to a conformational change at the active site, andis known as denaturisation.
