Slow Ca(2+) Efflux by Ca(2+)/H(+) Exchange in Cardiac Mitochondria Is Modulated by Ca(2+) Re-uptake via MCU, Extra-Mitochondrial pH, and H(+) Pumping by F(O)F(1)-ATPase

Mitochondrial (m) Ca(2+) influx is largely dependent on membrane potential (ΔΨ(m)), whereas mCa(2+) efflux occurs primarily via Ca(2+) ion exchangers. We probed the kinetics of Ca(2+)/H(+) exchange (CHE(m)) in guinea pig cardiac muscle mitochondria. We tested if net mCa(2+) flux is altered during a...
