Biology Ch 3 Enzymes

What Macromolecule are Enzymes?

Protein
What 3 Letters Do ALL Enzymes End In?

ASE
What Do Enzymes Do?
- Function is to speed up (Catalyze) reaction.
- control how fast "reactants" become "products"
All Enzyme reactions begin with__ and end with __?

Reactants, Product
Enzyme Substrate

A molecule upon which an enzyme acts
Where do substrated bind to enzymes?

Active site
Enzymes at Cellular Level are "Substrate Specific" what does that mean?

Enzymes are specific to substrates, if they can't fit, they will not go into enzyme
What is Denaturation?

When Enzyme breaks down losing shape and function due to temp. too high or PH incorrect
What is an Enzyme Inhibitor?

Chemical that interferes with enzyme activity
2 types of Enzyme Inhibitors
- Competitve
- Non-Competitive
Competitive Inhibitor
- Resembles substrate and competes for active site
Non-Competitive Inhibitor
- Bind to enzyme but they bind at a different site, not active site.
- This changes active site and renders it useless
Feedback Inhibition
- Quantity of Products are too high
- Result: Product becomes non-competitive inhibitor
Examples of Inhibitors
- Poisons and chemical warfare
- Pesticides
- Penecillin (inhibits bacteria)
