It has previously been shown that mitochondrial proton conductance decreases with increasing body mass in mammals and is lower in a 250-g lizard than the laboratory rat. To examine whether mitochondrial proton conductance is extremely low in very large reptiles, hepatocytes and mitochondria were prepared from saltwater crocodiles (Crocodylus porosus) and freshwater crocodiles (Crocodylus johnstoni). Respiration rates of hepatocytes and liver mitochondria were measured at 37 °C and compared with… CONTINUE READING
