Fig. 11. Transmission electron micrographs of gastric oxyntopeptic and pancreatic acinar cells of fasted (left) and fed (right) Python molurus. Note the numerous zymogen granules containing inactive enzymes within the oxyntopeptic cells of fasted pythons and within the acinar cells of fed pythons. By contrast, oxyntopeptic cells of fed snakes and acinar cells of fasted snakes possessed few zymogen granules. Scale bars, 1 µm.
