5.1 Study Guide Flashcards
What are enzymes?
Enzymes are catalysts which means they catalyze reaction which speeds them up.
Does every substrate have the same enzyme?
No each enzyme is specific to the substrate.
What are enzymes made of?
they are made of protein.
What is denaturation?
This is when the active site no longer functions.
What causes denaturation?
pH, Salinity, and Temperature.
What is activation energy?
The amount of energy needed for a reaction.
What is enzyme concentration?
The higher the concentration the higher the collisions.
Temperature.
The higher the temp, the higher the collisions but too hot can cause for denaturation.
pH
The higher the pH, the higher the collisions but if the pH is too high it can cause denaturation.
What turns and enzyme on?
Activators and cofactors which could also be called inorganic ions.
What turns an enzyme off?
inhibitors
what does a competitive inhibitor do?
it interferes with the active site by binding with the substrate.
What does a non competitive inhibitor do?
It changes the shape of the active sight.
What works more often to shut off the enzyme?
The noncompetitive inhibitor.
