... and anaerobic levator muscles. Dark levator muscle fibers from crabs ranging from <0.1 g to >190 g were examined with transmission electron microscopy to determine the density of mitochondria and subdivision diameters. Across all size classes, there was a constant mitochondrial fractional area(25...

... an unsteady locomotory gait increased significantly with water velocity, which resulted in an inverse relationship between exercise intensity and duration. We interpret this behaviour as evidence that unsteady swimming was being fuelled by the limited supply of anaerobic substrates in the white muscle...

... is the principal energy supply for eukaryotic cells, but when the P O falls below a critical mark metabolic switches turn off mitochondrial electron transport and activate anaerobic glycolysis. Without this switch cells would suffer an immediate energy deficit and death at low P O . An intriguing feature...
