Figure 3-3. (a) Electron Micrograph of a Single Mitochondrion in a Cell 

 from the Proximal Convoluted Tubule of Mouse Kidney, showing numerous 

 regularly spaced cristae. Electron-dense granules are visible near opposite 

 ends of the mitochondrion; (b) Enlargement of the Mid-portion of the 

 Mitochondrion in (a), showing the continuity between the cristae and the 

 inner of the two limiting membranes (arrows). (From Dalton, A. J. and 

 Felix, M. D., 1957. "Electron Microscopy of Mitochondria and the Golgi 

 Complex," Symp. Soc. Expt'l. Biol, 10, Figs. 4A and 4B, Plate 2.)
