Abstract

1. 1. In agreement with findings on mammalian brain, respiration of turtle cerebral cortical slices was stimulated by ouabain and high K + in the external medium. 2. 2. The effects of 40 mM K + and 10 −4 M ouabain on brain respiration were not significantly additive. 3. 3. The possibility that mitochondrial “Ca-respiration” accounts for both K +-induced and ouabain-induced stimulation of brain slice respiration is discussed. 4. 4. In contrast to brain, respiration of urinary bladder tissue was slightly depressed by 40 mM K + in the external medium. 5. 5. Ouabain (10 −4 M) depressed bladder oxygen consumption by approximately 20 per cent in the presence of both 2 and 40 mM K +.
