Abstract
Excised gill pieces of Mytilus edulis incubated at 25°for one hour with 14C-glucose took up 14C-glucose. Glucose taken up by the gills rapidly incorporated into glycogen in one way and was oxidized to respiratory CO2 in another. Dinitrophenol and monoiodoacetic acid which inhibited crawling velocity of the gills, inhibited the glucose incorporation into the gill glycogen. It was also shown by autoradiographic study that metabolically active glycogen was concentrated into the intercellular spaces abutting on the ciliated cells inside of a ciliated groove. Thus, we concluded that ciliary movement relates closely with the metabolism of glycogen in the intercellular spaces abutting on the ciliated cells inside of a ciliated groove.
