Metabolism of 14 C-Glucose by Metacercariae of Clinostomum campanulatum (Trematoda)

Abstract
Metacercariae, in vivo, absorbed more glucose-U-l4C and incorporated more radioactivity into glycogen than did in vitro forms. Metacercariae, in vivo and in vitro, incorporated glucose-U-l4C carbon into alanine, glutamic acid, glutamine, proline, and alpha ketoglutaric, citric, fumaric, lactic, pyruvvc, and succinic acids. The labeling patterns obtained indicate that the metacercariae of Clinostomum campanulatum possess the components of a TCA [tricarboxylic acid] cycle.
