Fig. 7. Aminopeptidase-N (APN) and maltase activity averaged over all sampling periods for each intestinal segment (A, B, C, D and E) of Python molurus. Note the decline distally in activity for both hydrolases. In this and the following bar graphs, error bars indicate ± 1 s.e.m. and different letters above the bars denote significant (P<0.05) differences between means as determined from post-hoc pairwise comparisons.
