Enzymes are organic molecules that are highly specific catylists for biological chemical reactions. Enzymes are not permanently changed by the reactions that they catalyze, although the may transiently change shape a little during the reaction. At the end of the reaction, the enzyme is the same shape that it was at the beginning.
While the structure of an enzyme can, and often does, change over the course of a reaction, after a reaction has completed, enzymes are returned to their starting state. It is worth noting that certain cofactors (such as ATP or GTP) may also need to be replaced in order for the reaction to procede again.
The product of the chemical reaction is released from the active site of an enzyme. The substrate is converted into product during the enzymatic reaction, and once the reaction is complete, the product is released to allow the enzyme to catalyze another reaction.
The region where reactants bind to an enzyme during a biochemical reaction is called the active site. It is a specific region on the enzyme where the substrate binds, forming an enzyme-substrate complex that leads to the catalysis of the reaction.
Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again.
Enzyme reaction rates are influenced by pH because enzymes have an optimal pH at which they function most effectively. Deviation from this optimal pH can denature the enzyme, rendering it less active or inactive. pH affects the enzyme's shape and charge, which in turn affects its ability to bind to the substrate and catalyze the reaction.
An enzyme speeds up your reaction in your body.
The enzyme does not undergo any permanent changes during the catalytic reaction; it simply facilitates the reaction by lowering the activation energy. At the end of the reaction, the enzyme is released unchanged and can participate in further reactions.

A specific enzyme is an enzyme that only changes the speed of ONE reaction. (It only acts on one particular substance that happens to be compatible with that enzyme) i.e. if enzyme A is specific to reaction A, it will change the speed of reaction A. However it will have no effect on any other reaction like reaction B or C.

In the enzyme reaction conical tube, you would likely observe a faster rate of reaction and a decrease in substrate concentration over time as the enzyme catalyzes the reaction. In the control reaction conical tube, you would not see significant changes in substrate concentration or reaction rate since there is no enzyme present to facilitate the reaction.
ENzyme
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.

An enzymes structure is not affected by a reaction. The enzyme has the same structure at the end of the reaction as it did before it took place. Note: Enzyme structures may change during the reaction itself but will return to their original shape etc when the reaction is complete.
