enzyme- substrate complex
ES Complex
The active site of an enzyme is the site where substrates undergo the reaction specfic to that enzyme.
lock-and-key model
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.
Where the substrate and the enzyme fit is called the active site. There are substance that can inhibit this fit.Natural poisons are often enzyme inhibitors that have evolved to defend a plant or animal against predators. These natural toxins include some of the most poisonous compounds known.
On one part of an enzyme is an active site (which is what the substrate binds to) that is shaped a certain way, say a triangle. A substrate that's in the shape of a square won't fit onto the triangle/the enzyme - but a substrate that has an indent in the shape of a triangle will. The way an enzyme recognizes its substrate is if it can attach itself to the enzyme's active site.
The substrate fits inside the active site of the enzyme. when it fits perfectly its called " lock and key"
That is the active site. Substrate binds to it

lock and key theory
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.
A subtrate is a reactant an enzyme acts off of. This fits into the active site and turns into the products
isomer position
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.

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.
This concept is called an induced fit.
