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.
What else can I help you with?
Why do enzymes have to fit the substrate exactly?

If several enzymes fit the same substrate they would be considered what?
They would be considered competitive enzymes because they are able to bind to the same substrate and compete for it.
In the induced fit model of enzymes a substrate associates itself with which part of an enzyme?
In the induced fit model of enzymes, a substrate associates with the enzyme's active site. This active site undergoes a conformational change upon substrate binding, allowing for a more precise fit between the enzyme and the substrate. This dynamic interaction enhances the enzyme's catalytic efficiency and specificity, facilitating the conversion of the substrate into products.
What do enzymes have to help them fit their substrates the molecules that attach to the enzymes?
They actually bind to a substrate as the term reactant is usually used in chemistry. They fit into what we call an active site just like a key will fit into a lock. The key must be the correct key or the reaction will not occur. So the enzyme is said to be specific for that 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.
What is the name of an enzyme only acts on one substrate?
Most enzymes are substrate specific because they have a specific shapes active site in which only a specific substrate can fit.
What refers to the situation in which the binding of a substrate to the enzyme causes a change in the enzymes shape facilitating an enzymes function?
This situation is known as induced fit. When a substrate binds to an enzyme, the enzyme's shape can change to better accommodate the substrate, creating a more optimal environment for the catalytic reaction to occur. This induced fit mechanism helps enzymes to be more specific and efficient in their function.
What are denatures?
Enzymes that have passed the optimum temperatue, and their active site breaks down so no substrate will fit into it.
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
What feature of enzymes controls which substrate they act on?
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. =)
How the lock and key model and the induced fit model differ?
According to lock and key model both the enzymes and the substrate possess specific geometrical shapes that fit exactly into one another. WHILE According to the induced fit model enzymes are more flexible structures and their active site is reshaped as substrate interacts with the enzymes.
Where does an enzymes join with a substrate?
The enzyme substrate complex
