RESUMO
Acetylcholine (ACh) and acetylcholinesterase (AChE) in central nervous system (CNS) and foot muscle (FM) of Laevicaulis alte cresting at 0400 h under LD 12:12 (0600 to 1800 : 1800 to 0600 h) regimen are in phase with each other. Nuli hypothesis (Ho) than for FM AChE, was rejected (A not equal to 0) since F (2,3) (0.05) greater than 9.6 ACh and AChE rhythm phase synchronized motor rhythm of Laevicaulis alte.

Succinate dehydrogenase (SDH) in central nervous system (CNS) and food muscle (FM) crested at 0400 h while in midgut gland (MG) it was out of phase. The average enzyme level (in per cent) was high during dark h half cycle (data points at 2000, 0000 and 0400 h) in CNS and FM and opposition prevailed for MG. Null hypothesis (Ho) was accepted (Ho = A = O) for CNS and rejected (Ho = A not equal to O) for MG and FM. The characteristics of the rhythm in CNS and FM correspond to motor functions, while in MG to energy source.
