the internal membrane system of a cell
(a)
this system of membranes is so extensive it accounts for more than half the total membrane in a cell
(a)
functions as an "intracellular highway"
(a)
"provides a path along which molecules move from one part of the cell to another"

The smooth ER __________
has no ribosomes
is located near the rough ER

rough ER
smooth ER
Golgi apparatus
mitochondria
After proteins are finished inside the Golgi apparatus, they may be
stored inside the cell
sent outside of the cell
stored inside the cell OR sent outside the cell
None of these answers are true.

rough ER
smooth ER
Golgi apparatus
lysosome
vesicles are
large and oblong
large and spherical
small and oblong
small and spherical
Which of these is NOT surrounded by a membrane?
ribosome
vesicle

Which happens first during the production of proteins?
Functional proteins are packaged in vesicles and leave the Golgi apparatus.
Vesicles transport proteins to the Golgi apparatus.
Proteins are assembled by ribosomes on the rough ER.
The Golgi apparatus modifies the proteins.
After they are completed, proteins travel to the cell membrane to be released outside the cell. What do they travel in?
(a)
Vesicles (a) with the cell membrane in order to release newly formed proteins outside the cell.
