Definition of Enzyme
Cut and join the molecules of life
Definition of Substrate
The substance on which an enzyme acts
Definition of Active Site
The region of an enzyme that binds to a protein or other substance during reaction.
Definition of Activation Energy
The minimum amount of energy that is required to activate atoms or molecules.
Properties of Enzymes
Reaction Specific- Each enzyme=Specific Substrate
Not consumed in reaction-Single enzyme=Lots of reaction
Made of proteins (Sometimes RNA)
Affected by celluar conditions- Denatured by certain temperatures or concentrations of ions.
Substrate Concentration
The more Substrate concentration the more enzyme reaction.
Enzyme concentration
The more enzymes the more reactions. It stabilizes because soon an enzyme would have to run into another enzyme.
Temperature
The higher the temperature the more the molecules move faster so they will have more successful collisions. If too hot bonds will break in enzyme and denaturation will happen.
pH
If you change the pH too much it can cause it to denaturalize.
How would you maximize enzyme activity considering all of the factors discussed in class? Minimize?
You would want to make sure all the factors are at their optimal level.
Compare and contrast inhibition and activation of enzymes
Enzyme activation enhances an enzyme’s activity by allowing it to bind. Enzyme inhibition reduces activity,
