abstract：:Nitric oxide is a small potentially toxic molecule and a diatomic free radical. We report the interaction of L-arginine, oxygen and calcium with the synthesis of nitric oxide in heart mitochondria. Nitric oxide synthesis is increased in broken rat heart mitochondria compared with intact and permeabilized mitochondria....
