...Kenneth C. Welch, Jr; Douglas L. Altshuler; Raul K. Suarez SUMMARY The stoichiometric relationship of ATP production to oxygen consumption,i.e. the P/O ratio, varies depending on the nature of the metabolic substrate used. The latest estimates reveal a P/O ratio approximately 15% higher when...

... increase was higher for states 4 and 4+ than for state 3 respiration. Exposure of oyster mitochondria to 35°C resulted in a decreased respiratory control and phosphorylation efficiency (P/O ratio)compared to that of the acclimation temperature (15°C), while an intermediate temperature (25°C) had no effect...
