| Abstract: | - 1.1. Activities of nine glycolytic and related enzymes were measured in lantern muscle extracts of the echinoids Arbacia lixula, Echinometra lucunter and Lytechinus variegatus.
- 2.2. The specific activities of these enzymes were comparatively low, being often the highest in L. variegatus and the lowest in A. lixula. The major differences referred to HK, PGK and G-6-PDH activities.
- 3.3. Noticeable differences in LDH activities were recorded in comparison with other invertebrate muscles. The implications of these results are discussed.
