Enzyme-substrate complex Flashcards
(6 cards)
1
Q
Describe the active site of an enzyme
A
the pocket on the enzyme where an enzyme
catalyzed reaction takes place
2
Q
What is a substrate?
A
the molecule bound in the active site and acted upon by the enzyme
3
Q
What is a simple enzymatic rxn?
A
E+S <—-> ES<—->EP<—–> E + P
E: enzyme
S: substrate
P: product
ES and EP: Transient complexes
4
Q
Equilibrium of rxn is reached when
A
no net change in the
concentrations of reactants and products —> NOT affected by enzymes
5
Q
Rate of rxn:
A
: V = d [P]/dt (Ms-1) —> how quickly or slowly a reaction takes place
catalysts including enzymes increases the rate [S↔P:V = k [S] (k: rate constant)]
6
Q
K =
A
rate constant
