Fig. 7. Modeling of H,K-ATPase-rich membranes from a 0.4 µm thick section reconstructed by tomography. (A) A section is depicted from which membrane profiles were accumulated and stacked into objects of individual color. A partial mitochondrion (red contours) is included for size comparison and orientation. The insert shows an actual tomographic section, near the middle of the stack, outlining the membrane structures that were included in the model. (B) The model of tubulocisternae has been meshed and rotated to provide another view. The mitochondrial object is still represented as contours.
