...Jarren C. Kay; Jocelyn Ramirez; Erick Contreras; Theodore Garland, Jr ABSTRACT Muscle pH decreases during exercise, which may impair function. Endurance training typically reduces muscle buffering capacity as a result of changes in fiber-type composition, but existing comparisons of species...

... and calculated respiratory exchange ratios suggest that catabolism of haemolymph proteins may contribute to a reduced haemolymph buffering capacity, and thus a compromised ability for CO 2 accumulation, in solitary locusts. Nevertheless, DGC was lost at similar hydration states in the two phases, suggesting...

... at a pressure of 4-5 kPa almost completely blocked their capacity for motility. Furthermore, exposing semen to increasing partial pressures of CO 2 up to about 1 kPa resulted in a marked decrease in semen pH. These observations are consistent with the findings that the buffering capacity of semen...

... of protons and/or high tissue buffering capacity. Second, although the functioning of the pentose phosphate pathway has been strongly inferred from measurements of enzyme activities ( Boström et al . 1972 ; Pelster and Scheid, 1991 ), and from measurements of enhanced rates of CO 2 excretion relative...

... to the toadfish hepatocytes extend to the eel hepatocytes, then imidazole-like, temperature-sensitive buffering capacity was probably artificially elevated, but by only 9.4%. It is reasonable to conclude, then, that the results of Walsh and Moon (1983) were little biased by the addition of Hepes to the external...
