Higher magnification of acidosomes of Figure 3 docked at the nascent
digestive vacuole membrane. The E-fracture face is relatively IMP free
while the P-fracture face (Pac) has many large IMPs
as well as some sizable pits where chunks of this leaflet seem to have
stuck to the E-face. Tiny pits on the E-face (Eac)
indicate the removal of individual IMPs from this leaflet. An
indentation (arrow) of the membrane into the lumen of the
acidosome shows IMPs on its exposed P-face; which, if any, of these
IMPs are V-ATPases is not known. c, cilium. EM taken on 5/26/92
by R. Allen with Zeiss 10A TEM. Neg. 19,800X. Bar = 0.2µm. Published
in J. Cell Sci. 106:411-422, 1993.
