THE EFFECT OF PIPERAZINE ON SUCCINATE PRODUCTION BY ASCARIS LUMBRICOIDES

Abstract
Piperazine reduced the production of succinate by Ascaris lumbricoides. This effect was reversible. There was a close parallelism between the concentrations of piperazine which paralysed the worm and those which inhibited the formation of succinate. Piperazine did not affect the incorporation of [2‐14C]lactate into succinate by strips of Ascaris muscle. It was concluded that production of succinate supplies energy for the contraction of Ascaris muscle.
