100
The spot on an enzyme where the substrate binds
What is the active site?
100
A molecule that binds to the active site of an enzyme, therefore blocking the substrate's ability to bind, it known as __________. _________
competitive inhibitor; competitive inhibition
100
This variable is manipulated by the researcher

100
This is the classification of biomolecules that enzymes belong to:
What is "protein?"
200
This is the molecule that binds to an enzyme in its active site
What is the substrate?
200
Substrates fit into the active site of a substrate as a ________ fits into a _____________
key; lock
200
When an inhibitor binds to the allosteric site of an enzyme, changing the shape of the enzymes and subsequently the active site, it is known as _____________ ___________
noncompetitive inhibition; noncompetitive inhibitor

300
The ability of an enzyme to undergo a conformational change in order to achieve a "perfect fit" for a substrate
What is Induced Fit?
300
___________ are inorganic molecules that aid enzyme function by stabilizing protein structures or participating directly in catalysis (usually minerals)
