Concentration - Effect curves Flashcards
What is the theoretical relationship between concentration and effect?
linear relationship
What line determines the relationship between concentration and effect?
hyperbolic line = non-linear relationship
what is the role of the log-transformation (graph)
used to view the data link between the concentration and effect
which coefficient theory supports the Emax model?
Hill coefficient theory
what is the hill coefficient theory?
Haemoglobin has 4 binding sites for O = as each is filled, the affinity for oxygen of the others increases
what happens to the affinity of the drug as more receptors are occupied?
affinity for the drug increases
What happens to the number of sites occupied as the concentration increases?
number of sites increases
What is the law of mass action?
Chemical principle that proposes that the rate of a chemical reaction is proportional to the product of the concentration of the reactants
What is the Emax model?
E= Emax[D]/EC50 + [D]
Model that describes experimental data mathematically
