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.
The substrate fits inside the active site of the enzyme. when it fits perfectly its called " lock and key"
active site
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.
Hydroxylamine is a competitive inhibitor. It fits onto the active site(the place where chemical reactions occur on an enzyme) of an enzyme, but it does not react. This causes the hydroxylamine to compete with the normal substrate for the active sites on the enzymes.

enzyme- substrate complex
nothing.
have a shape that fits into the enzyme
lock and key theory
I have an enzyme with activity 218 u/mg enzyme, How can I pick up 0.12 u/ml enzyme?
That is the active site. Substrate binds to it
The active site of an enzyme is the site where substrates undergo the reaction specfic to that enzyme.
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.
An enzyme in a biochemical reaction fits this definition.
