Which feature of the kinetics of l-alanine transport would provide evidence that dom is an important source of nutrients under low-food conditions?
high affinity transport (kt) of l-alanine

-under low food conditions, the capacity of transport is irrelevant as no transporters are saturated with l-alanine
-however, the transporter's affinity for l-alanine would be important as only high affinity transporters will be able to facilitate l-alanine uptake at low concentrations
