The reason why an enzyme fits a specific substrate is due to its 3rd dimensional shape. Enzymatic competition involves competition among several different available enzymes to combine with a given substrate material.

What is a substrate that fits into an area of an enzyme?
The substrate fits inside the active site of the enzyme. when it fits perfectly its called " lock and key"
What fits with an enzyme to make a reaction occur?
The substrate fits into the enzyme, much the way a key fits in a lock. Sometimes there are other "modulators" that also fit in the enzyme.
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.
As an enzyme fits into a substrate at the active site it undergoes a slight change in order to fit into the substrate. this process is defined by a concept called?
This concept is called an induced fit.
Compare enzyme activity with a lock and key?
Lock and key is an analogy of enzyme catalysis in a cellular reaction. The lock and key are compared directly to the substrate and enzyme, because of the high specificity of their physical shape. Enzymes participate in the reaction they catalyze. The reactant molecule (substrate) binds to the enzyme molecule at a particular location called the active site. (this is compared to the lock with keyhole) The highly specific nature of an enzyme is due to very precisely defined arrangement of atoms in the active site(again, this is the lock in the analogy). The substrate molecule must have a matching shape (here is the key) that will fit into the active site. The bond breaking and bond forming processes that transform the substrate into products occur while the substrate is bound to the active site of enzyme. In other words its something like a jigsaw puzzle where the substrate fits into the enzyme. The reaction occurs and the substrate then leaves the enzyme as products. ( Not my work.

When a substrate fits into an active site of an enzyme what is formed?
enzyme- substrate complex
What is the surface region of an enzyme into which substrate molecule fits?
That is the active site. Substrate binds to it
What happens When an enzyme's substrate fits into enzymes?
nothing.
Which describes a model of a process in which the substrate fits into the active site to form a substrate enzyme compound?
lock-and-key model
What happens after a substrate binds to an enzyme?
Substrate a reactant molecule that binds to an enzyme. It has a specific shape that is complementary in shape to the active site of the enzyme. Product the substance or substances produced by the reaction between the enzyme and substrate.
What is the place where the substrate attaches to the enzyme?
The active site of an enzyme is the site where substrates undergo the reaction specfic to that enzyme.
What is key and lock theory?
It is when the enzyme (lock) fits exactly into the substrate (key) forming an enzyme substrate complex. It refers to enzymes and their substrates. The enzyme has an active site (lock) where the substrate that is complemetary fits in (key). Only substrates that fit perfectly into the enzymes active site will active the particular reaction, just like only 1 specific key will open a door.
When enzyme fits into substrate at an active site?
lock and key theory

What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
