-
six classes of enzymes
oxidoreductase, transferases, hydrolases, lyases, ligases, isomerases
-
hydrolases
ACP, ALP, AMY (amylase)
-
oxidoreductase
LD, g-6-pdh
-
transferases
AST, ALT, CK, GGT
-
Enzymes catalaze physiologic reactions by
lowering the activation energy that substrate must reach
-
One major influence on enzymatic reactions
substrate concentrations
-
With the amount of enzyme exceeding the amount of substrate reaction rate
increases steadily as substrate added
-
first order kinetics
reaction rate is directly proportional to substrate concentration
-
when substrate concentration is high enough to saturate all enzymes
Velocity reaches its max
-
zero order kinetics
dependent only on enzyme concentration
