active site
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"
No. Only amylase works for breaking-down of glucose( in fact the product should be maltose. It is because of lock-and-key hypothesis, only 1 enzyme fits the specific substrate. By the way, catalase is a enzyme inside liver, it is used to break down the hydrogen peroxide, the products are oxygen and water.
The substrate.
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. Found it on Yahoo Answers.....Do not give me credit...Thought I should do this to help people out =] ) Edited answer for readability and clarity - thanks!
That is the active site. Substrate binds to it

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.
enzyme- substrate complex
nothing.

What id actually says is... What fits in the blank? Diagonal AC of Parallelogram ABCD _____ bisects angle A and angle C.
Enzymes are complex molecules with intricate structure. It may help to think of them as being somewhat like keys: a key only opens the locks it fits, and enzymes only catalyze reactions where the molecule fits properly with the enzyme's active site.
have a shape that fits into the enzyme
