Speeds up the rates of chemical reactions by providing energy for the cell to use. Thus, the cell is not working as hard to perform the task. You need enzymes to survive. That is one of the reasons why a high temperature fever is a problem, the enzymes that help to keep you alive are denaturing (basically being rendered useless) and without them you cannot live.
-speeds reactions by lowering activation energy.
-provides a site that reactants can react to each other.
There are actually 3 things. Enzymes can break down a substrate, combine two smaller substrates together or they can not do anything to the substrate because they are denatured.
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else.
A substrate
The substrate binds to the active site.
Temperature/pH/Substrate Concentrate and Inhibitors
The substance on which enzymes act are called substrates.
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else.

The enzyme substrate complex
in an enzyme-substrate complex, the enzyme acts on the substrate .
Competition among various enzymes for same substrate
enzymes are compared to a substrate.
The substrate binds to the active site.
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.
