The feature of enzymes that controls they substrate they act on is called the active site of the enzyme. The enzyme is a protein. Each active site is specific too the substrate which it acts on. The substrate may fit into the active site via a lock and key mechanism or by an induced fit. The active site attracts and binds with the substrate in order to allow a reaction to occur faster. The substrates are also called the reactants. =)
What else can I help you with?
The molecule on which an enzyme acts is called an?
The substance on which enzymes act are called substrates.
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.
What are the molecules that enzymes act on called?
The molecule upon which an enzyme acts is called the substrate.
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.
How fast do enzymes act?
Enzymes reaction cycle is so fast that a single enzyme molecule typically act on about thousand substrate molecules per second.
What is the substance that a catalyst works on?
The substrate on which a catalyst works is called its substrate
What are the Examples of intra cellular enzymes?
RNA/DNA polymerases - Reverse Transcriptase. Helicase. Binding proteins. Enzymes simply act on a substrate - there are tonnes.
Why do enzymes generally only bind to one 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.
If Pectinase only breaks down pectin and It has no effect in cellulose What term is used to describe this characteristic of enzymes?
Enzymes are substrate specific; meaning that their active site only allows for a certain substrate to bind - in this case, pectin, and the enzyme has no effect on any other biological molecules
How many substrate molecules does a typical enzyme act on per second?
A single enzyme molecule can act on about 1000 substrate molecules per second.
Substrate molecules bind to enzymes where?
The bind in the active site.
Molecule that binds to an enzyme?
A molecule that binds to an enzyme is usually referred to as a substrate. Substrates are the molecules on which enzymes act to catalyze a biochemical reaction. Upon binding to the enzyme's active site, substrates undergo a chemical transformation to form products.
