in order to test the hypothesis that na+ , k+-atpase ( na+ , k+-dependent atpase ) is involved in the noradrenaline-mediated stimulation of respiration in brown adipose tissue , the effects of noradrenaline on na+ , k+-atpase in isolated brown-fat-cell membrane vesicles , and on 22na+ and k+ ( 86rb+ ) fluxes across the membranes of intact isolated cells , were measured .
