6.3 enzyme kinetic equations Flashcards
given A+B—> P what what does that mean
A and B are reactants p is the product
how is rate expressed
quantity of A or B (concentration) in a given time interval
-delta A/ delta t is equal to
-delta B/ delta t = delta P/ delta t i
rate constant
rate of rxn is proportional to prodcut of the [] of the reactants.k is the rate constant. rate = delta P/ delta t = k[A][B]
is k the rate constant dependent on temp
yes
the higher the value of k or the great the conetration of reactants, the rxn is
faster
what does the shape of the concertation of product vs time indticate
velocity decreases as substrate concetration decreases. flattening of curve means eqlbrm is reaches, saturation of substrate
first order A–> P depends on
rate constant and concetration of A/one substrate
second order rate constants A+B—> P deoend on
rate cosntants and and substrets
what are pseudo first order rates
A+B—> P. B is present in excess and A is present in low concetratoions. will be first order w.respect to A and will not depend on B. rate= k[A]1[B]0
zero order rate constants
rate=k, not dependednt on concetration of reactants but some other factores such as presence of catalyst
