Ca(2+)-dependent activation of citric acid cycle enzymes has been demonstrated in isolated cardiac mitochondria. These observations led to the hypothesis that Ca2+ is the signal coupling myofibrillar energy use to mitochondrial energy production in vivo. To test this hypothesis we have measured mitochondrial Ca2+ content during increased energy demand, using electron probe microanalysis. Mitoch...
