How does an enzymes active site relate to its substrate?
The substrate binds to the active site.
How does an enzymes active site relate to it's substrate?
The substrate binds to the active site.
How enzyme structure makes an enzyme very specific?
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.
Why will only certain substrate molecules fit into the active site?
It will only bind with the enzymes active site of the shapes are complimentary and enzymes are very specific
Why am enzyme can be used to catalyst a large quantity of substrate?
Many times enzymes have multiple active sites that allow for many simultaneous reactions. For example, it's possible to have a fourth of the number of enzymes as substrate molecules, but the enzyme may have four active sites, resulting in one active site per substrate molecule.
What would be unlikely to contribute to the substrate specificity of an enzyme?
The allosteric site is distinct from the active site, and does not affect the substrate specificity of the enzyme
How does an enzymes active relate to its substrate?
The substrate binds to the active site.
How does an enzymes active site relate to its substrate?
The substrate binds to the active site.
How does an enzymes active site relate to it substrate?
The substrate binds to the active site.
How does an enzymes active site relate to it's substrate?
The substrate binds to the active site.
How might an amino acid change at a site distant from the active site of the enzyme alter the enzyme's substrate specificity?
The alteration of an amino acid on a site other than the active site will: change the shape of the protein.
Substrate molecules bind to enzymes where?
The bind in the active site.
The specificity of an enzyme is due to its active siteThe active site is a shape only a certain?
An enzyme's active site will bind with only a specific substrate. Any other kind of substrate will be rejected by the active site.
How does an enzymes activate site relate to its substrate?
The substrate binds to the active site.
What happens if enzymes loose their specificityAsk us anything?
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.
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.
Why do enzymes generally bind to only type of substrate?
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else.
