~Most of the phospholipids of the endomembrane system are synthesized
in the mitochondria.
,~Mitochondria function in the modification and sorting of lipids and
proteins.
~Proteins that will be secreted from the cell are likely to be found in closed
spaces bounded by membranes of the endomembrane system.
~Ribosomes move lipids and proteins among the different organelles of
the endomembrane system. - ANSWER
Proteins that will be secreted from the cell are likely to be found in closed
spaces bounded by membranes of the endomembrane system.
A cell has formed a food vacuole as it ingested a food particle. Which of
the following events is associated with the breakdown of that food
particle?
~proteins for digestion of the food particle were initially processed in
mitochondria
~digestion of the food particle occurs in a vesicle enclosed by a
membrane that separates the digestion from the cytoplasm
~the membrane of the food vacuole is derived from the cell wall
~proteins for digestion of the food are made by ribosomes in the Golgi
apparatus

from the cytosol - ANSWER digestion of the food particle occurs in a
vesicle enclosed by a membrane that separates the digestion from the
cytoplasm
