Figure 4. Tomographic Reconstruction of an eat-3(ad426) Mitochondrion.

(A,B) Front and rear views of an eat-3 mitochondrion reconstructed by electron tomography. Outer membrane is shown in red. Inner membrane is shown in green. Bubbles on the side of the mitochondrion, which are also shown in green, are matrix compartments separated inner membrane septae. Invaginations of the inner membrane, which are likely to be short tubular cristae, are shown in light green. Internalized membrane-bound compartments are shown in magenta. Large clusters of electron dense material without membrane are shown in blue. (C–F) Tomographic sections used to make the three-dimensional renderings in (A) and (B). The bar is 0.5 µm.
