Lactate efflux from sarcolemmal vesicles isolated from rainbow trout Oncorhynchus mykiss white muscle is via simple diffusion.
Lactic acid is produced as an end product of glycolysis in rainbow trout white muscle following exhaustive exercise. The metabolically produced lactic acid causes an intramuscular acidosis that must be cleared, either via net transport out of the muscle or by conversion to glycogen, thereby replenishing the muscle energy store. Trout muscle has been shown to retain lactate and utilise it as a s...
متن کاملLactate transport by rainbow trout white muscle: kinetic characteristics and sensitivity to inhibitors.
This study used an isolated-perfused tail-trunk preparation of rainbow trout to examine the uptake and release of lactate (Lac) and metabolic protons (delta H+M) in resting and exercised fish white muscle. In exercised muscle, L(+)-Lac efflux was inhibited (approximately 40%) by 5 mM alpha-cyano-4-hydroxycinnamate (CIN), but not by 0.5 mM 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid...
متن کاملLactate transport across sarcolemmal vesicles isolated from rainbow trout white muscle.
Rainbow trout (Oncorhynchus mykiss) retain the majority of lactate produced during exhaustive exercise within white muscle. Previous studies have suggested that this retention is partially via a re-uptake of released lactate. The purpose of this work was to study lactate uptake using trout white muscle sarcolemmal vesicles. Lactate uptake by trout white muscle is partially through a low-affinit...
متن کاملThe Antioxidant Vitamin (A, C, E) and the Lipid Peroxidation Levels in Some Tissues of Juvenile Rainbow trout (Oncorhynchus mykiss, W. 1792) at Different Oxygen Levels
In this study, the malondialdehyde (MDA) levels in the muscle, liver and kidney tissues and the antioxidant vitamin (A, C, E) levels in the muscle tissue of juvenile rainbow trout were investigated under different oxygen levels (3.5 mg O2/l, 4.5 mg O2/l and 7 mg O2/l) at the end of the 8 hour trial. Fish (initial weight and length, 30.19±2.2 g and 13.15±0.22 cm, respectively) were distributed i...
متن کاملRespiratory and metabolic functions of carbonic anhydrase in exercised white muscle of trout.
Electrical stimulation of a trout saline-perfused trunk preparation resulted in metabolic and respiratory responses comparable to those occurring after exhaustive exercise in vivo. Recovery of intracellular acid-base status and glycogen resynthesis were faster than in vivo. Intracellular carbonic anhydrase (ICF CA) blockade elevated intracellular[Formula: see text] relative to untreated postexe...
