all enzymes are proteins but not all proteins are enzymes
all reactions in the body are mediated by enzymes, which are protein catalysts that increase the rate of reactions without being changed in the overall process
substrate 
enzyme's selective channel into useful pathways
enzyme directs all metabolic events
oxidoreducterase
catalyzes an oxidation-reduction reaction
organic oxidation
oxidation that increases the number of C-O bonds and/or decreases the number of C-H bonds
oxidation reduction
reduction that decreases the number of C-O Bonds and/or increases the number of C-H bonds
transferases 
catalyzes the transfer of a functional group other than hydrogen from one molecule to another
hydrolases 
catalyzes a hydrolysis reaction in which the addition of a water molecule to a bond causes bonds to break
Hydrolysis reactions are central to the process of digestion
lyase
catalyzes the addition of a group to a double bond or removal of a group to form a double bond in a manner that does not involve hydrolysis or oxidation
isomerase 
the arrangement of a substrate in a reaction, converting it into a molecule isomeric.has only one reactant and one product in reactions where it is operative
ligase/synthetase
catalyzes bonding together of two molecules into one with the participation of ATP

Enzymes are protein catalyst that increase the velocity of a chemical reaction, and are not consumed during reaction
