Fig. 4.
Michaelis-Menten and Sigmoidal Hill kinetics for sodium-dependent and sodium-independent electrogenic glucose transport for trout in pyloric ceca (A), illustrated with representative trace on the right side (B) (sodium-dependent fish: n = 12; sodium-independent fish: n = 5); midgut (C), illustrated with representative trace on the right side (D) (sodium-dependent fish: n = 18; sodium-independent fish: n = 4); and hindgut (E), illustrated with representative trace on the right side (F) (sodium-dependent fish: n = 24; sodium-independent fish: n = 4). The maximal velocity (Vmax) and Michaelis-Menten constant (Km) are represented in pyloric ceca (A) for illustration. Values are means ± SE. Isc, short-circuit current.
