PSIO 303 BLOCK 2 L6 Exam Study Guide
Solutions
List and discuss the diagnostic characteristics of passive diffusion. - ANSWER-ALL channels, and
SOME carriers, can only support NET transport DOWN the electrochemical gradient of their transported
substrates
One category of carrier can do somethi...
As [S] continues to increase, the rate of transport begins to approach a maximum value
At high enough substrate concentrations, the carrier-mediated process can be expected to 'saturate'
In the context of cellular physiology, describe the importance of the kinetic parameters J max and K t -
ANSWER✔✔-J max = maximal rate of a carrier-mediated transport system, product of the number of
transporters x the
turnover number
K t = equal to the substrate concentration that produces 'half-maximal' transport when the rate of
transport is
equal to J max /2)
Given either a Michaelis-Menton plot or an Eadie-Hofstee plot, deduce Jmax and Kt - ANSWER✔✔-
Michaelis-Menton equation: relationship between substrate concentration and the rate of transport
(revealing
the saturation of that rate) is generally described by the following equation:
J = rate of transport at a substrate concentration equal to (S)
J max = maximal rate of transport and reflects 'saturation' of the process.
