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.
