Adenosine triphosphate synthesis coupled to K+ influx in mitochondria

Science. 1982 May 14;216(4547):742-4. doi: 10.1126/science.6281882.

Abstract

The influx of K+ into swollen mitochondria in the presence of valinomycin results in the synthesis of adenosine triphosphate in which approximately one H+ disappears per adenosine triphosphate synthesized. The synthesis is blocked by atractyloside but is insensitive to oligomycin and relatively insensitive to uncouplers.
