|
what is an enzyme?
|
protein or RNA biological substance that acts as catalysts and help complex reactions occur everywhere in life
|
|
|
WHat is a catalyst?
|
a substance (enzyme) that can change the rate of a chemical reaction
|
|
|
What is a substrate?
|
biological molecule that the enzyme will work on
|
|
|
What is an active site and its job?
|
a pocket or group of the enzyme that fits around the substrate
|
|
|
What is the product?
|
is the changed substrate after catalysis
|
|
|
What is the catalysis
|
is the change in rate of a chemical reaction by reducing the amount of energy needed to start the reaction
|
|
|
How do enzymes work?
|
an enzyme and a substrate are in the same area. the enzyme grabs onto the substrate with its active site. Catalysis happens and the substrate is changed and broken down with other molecules to become something new
|
|
|
what 4 things can affect the way enzymes work. explain how they affect the enzyme
|
1.) temperature- if it changes, enzyme changes. messes up process and can't work
2.) activators make enzymes work harder and faster 3.) pH levels (measure of acidity)- acidity environment affects the shape, cant work 4.) inhibitors- slow down or stop enzyme. they bond ti the protein and the shape changes |
