Abstract/OtherAbstract:
1. Some glycolytic metabolites were determined for red muscle (RM) and white muscle (WM) of goldfish acclimated to 10 and 25 degrees C. 2. Lactate/pyruvate (L/P) was higher in RM than in WM. 3. Lactate dehydrogenase (LDH) of RM was slightly more susceptible to inhibition by lactate than WM-LDH. At L/P found in vivo under resting conditions, RM-LDH was about three times as inhibited as WM-LDH. 4. When 25 degrees C-fish were forced to swim at 25 degrees C, the increase of L/P in WM was mainly due to increased lactate level and that in RM was ascribed to decreased pyruvate level. These changes were obscure in 10 degrees C-fish.
