digestive system process
Cellular Component
food vacuole
Quick-freeze deep-etch image of a DV-III containing paracrystalline sheets in its lumen. The sheets have parallel rows of subunits spaced at 20nm center-to-center but the chemical nature of the sheets...

food vacuole
At the same time that the acidosomes fuse with the phagosome, the DV-I membrane, that originated from the discoidal vesicles, is transformed into tubules that are removed from the phagosome. By this p...

Cellular Component
cytoproct
The cytoproct is the cell’s defecation site where spent digestive vacuoles fuse with the plasma membrane. In this cell the cytoproct is closed and forms a ridge along the posterior suture on the ven...

endocytic vesicle lumen
In some cells exposed to horseradish peroxidase (HRP) for 30 sec and then immediately fixed some HRP has already entered the cell by endocytosis and has been removed from the early endosomes in carrie...

Cellular Component
early phagosome
Higher magnification of acidosomes docked at the nascent digestive vacuole membrane. The E-fracture face is relatively IMP free while the P-fracture face has many large IMPs as well as some sizable pi...

cell cortex
A micrograph showing the partially open cytoproct of Colpoda cucullus. The alveoli stop at the edges of the cytoproct and filamentous material (actin?) coats the inside of the single membrane that cov...

cell cortex
A high resolution micrograph showing the partially open cytoproct of Colpoda cucullus. The alveoli stop at the edges of the cytoproct and filamentous material (actin?) coats the inside of the single m...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
secondary lysosome
Secondary lysosomes in quick-freeze deep-etch images lie against the smooth E-face of a phagoacidosome (DV-II) membrane. The P-fracture face of one fairly large lysosome lies close to the DV-II but no...

NCBI Organism Classification
Paramecium multimicronucleatum
Biological Process
digestive system process
Cellular Component
secondary lysosome
Secondary lysosomes contain a fairly dense matrix in well fixed cells. The content of these lysosomes seems to be released as a package into the phagoacidosome when they fuse to form the phagolysosome...
