Lactate dehydrogenase (LDH; E.C. 1.1.1.27) is a crucial enzyme involved in energymetabolism inmuscle, facilitating the production of ATP via glycolysis during oxygen deprivation by recycling NAD+. The present study investigated purified LDH from the muscle of 20 h anoxic and normoxic T. s. elegans, and LDH from anoxic muscle showed a significantly lower (47%
