...Guy S. Hawkings; Fernando Galvez; Greg G. Goss SUMMARY Mitochondria-rich cells (MR cells) of the gills of rainbow trout undergo changes in relative distribution and biochemical function during acclimation to partial-strength (10‰) and full-strength (30‰) seawater. In isolated total gill cells, Na...

... be inactive. It may also explain why animal plasma membrane H + V-ATPases are commonly found in ‘mitochondria-rich’ cells. We suggest that the high oxygen affinity of cytochrome oxidase leads to localized reducing conditions near mitochondria which would allow H + V-ATPases to remain active in plasma...
