The transport of glutamine across a membrane was measured, and the results obtained are presented in the following table. What type of transport does Gln exhibit?

Question

The transport of glutamine exhibits saturation kinetics and is not dependent on ATP. Therefore, it is most likely facilitated diffusion. The table shows that as the concentration of glutamine is increased, there is a corresponding increase in the rate of transport until a maximum rate (Vmax) is reached. This suggests that the transport is mediated by a carrier protein that becomes saturated at high concentrations of glutamine.
