## Abstract The earthworm __Lumbricus terrestris__ is ammonotelic while feeding but becomes ureotelic with fasting. The metabolic sources of ammonia nitrogen in feeding worms have been examined. Two deaminating enzymes, L‐serine dehydratase and 5′‐AMP deaminase, have been observed to be present in

## Abstract The linear distribution of ammonia‐generating enzymes (L‐serine dehydratase and 5′‐AMP deaminase) along the gut of __Lumbricus__ has been examined using that of the digestive enzymes as a frame of reference. This study confirms the observations of earlier workers indicating a high acti
