What are catalysts?
Enzymes
Definition of catalyst:
Proteins that speed up chemical reactions
Definition of enzyme:
Protein
Definition of chemical reactions:
A process which reactants are converted into products
Definition of activation energy:
The minimum amount of energy that is required to activate atoms
Definition of substrate:
A reactant which bonds to enzymes
Definition of active site:
Where substrates fit into enzymes
What kind of reaction is this? Substrate + Enzyme > Enzyme - substrate complex > Enzyme + product 1 + product 2
Hydrolysis
What kind of reaction is this? Enzyme + product 1 + product 2 > Enzyme - substrate complex > Substrate + Enzyme
Synthesis
Higher temperatures in collision theory equal what?
More successful collisions
How are enzymes turned “on”?
Activators and cofactors
How are Enzymes turned “off”?
Inhibitors
What are the two kinds of Inhibitors?
Competitive and Noncompetitive inhibition
