Under effects of myocardial ischemia (30 min), the activities of the intermembrane enzymes of rabbit heart mitochondria, i.e., adenylate kinase and creatine kinase, are inhibited by 20% and 23%, respectively. Consequently, the creatine- and AMP-activated respiration of mitochondria diminishes by 52% and 39%, respectively. An inhibitory analysis of ADP-, AMP- and creatine-activated mitochondrial respiration performed in the presence of atractyloside has demonstrated that ischemia (30 min), adriblastin (0.688 mM) and succinate (10 mM) cause alterations in the functional coupling of adenylate kinase and creatine kinase with the adenine nucleotide translocator. These alterations lead to the diminution of the rate and efficiency of energy transfer from mitochondria to hexokinase, as an arbitrary site of energy consumption. An addition of cytochrome c to ischemic heart mitochondria results in an increase in the rate of ATP synthesis; however, the efficiency of this process is lowered. The toxic effect of the anticancer drug--adriblastin on heart mitochondria respiration is enhanced in the presence of creatine in the bathing solution.
