nopeeeee not at all.............they are just used to help the reaction go faster

Enzymes lower the activation energy in a chemical reaction which happens when a substrate binds the active site on the enzyme....

No. Enzymes are, by definition, catalysts. A catalyst is something which speeds up a reaction--by lowering the activation energy, as noted--but are not consumed in the process.

no, it just create another pathway for the reaction to occur by lowering the activation energy......the amount of the enzyme in the end of the reactions is still the same

Enzymes are used over and over again. Think of enzymes like a stapler:
1. Enzymes are specific - they only do one job. (I only use a stapler for stapling ... nothing else.)
2. Enzymes can be used over and over again. (Staplers can be used over and over. They aren't one-use tools.)
3. Enzymes are not changed during the reaction they catalyze. (The stapler isn't changed by use, but the papers are changed.)
