Term
What is the amino group on the amino acid molecule?
Definition
NH2
Term
What is the COOH part of an amino acid called?

Term
What does an enzyme do?
Definition
Lowers the activation energy which makes the reaction usually happen faster.
Term
What is a substrate?
Definition
The molecule which the enzyme is acting upon.
Term
What is the induced fit model of enzyme reactions?
Definition
This is where the shape of the enzyme and the shape of the substrate fit together.  This fit causes the substrate to either be broken down or bonded together.
Term
Explain competetive inhibition.
Definition
When an imposter shaped like the substrate will fill the active site, preventing the substrate from fitting.
Term
Explain non-competitive inhibition.
Definition
When the inhibitor binds to a location away from the active site.  This binding action causes the active site to alter its shape which renders the enzyme inactive.
