Enzymes Flashcards
What is an enzyme?
Is a protein (made up of amino acids)
Give 3 characteristics of an enzyme
Speed up reactions ( catalysts)
Act specifically on a particular substrate
They can be used over and over
Competitive inhibitors
Bind to active site on enzyme and block it from bonding to a substrate
If temperature and ph are too high/low the enzyme becomes
Denatured
Non competitive inhibitors
Bind elsewhere on enzyme and change the shape of the active site
Allosteric sites
Sites on the enzyme that stimulate or inhibit an enzymes activity - stabilize the enzyme in either the active or inactive form
Allosteric Activator
Binds to allosteric sites and stabilizes the proteins shape keeping all the active sites open
Allosteric inhibitor
Bonds to the inactive spots on an enzyme and stabilizes them
What is the function of an enzyme?
Enzymes guide and control all the chemical reactions in the body.
