1. Lungfish erythrocytes (RBC), unlike those in other species of fishes, oxidize endogenous glutamate at a higher rate than they oxidize glucose. This pattern closely resembles that found in invertebrates. 2. The exogenous glutamate oxidation rate of RBC from most species of fish as well as other groups of vertebrates is approximately equal to or less than that observed for glucose. 3. These findings suggest that the nucleated RBC of most vertebrates appear to rely less on the TCA cycle for… CONTINUE READING
