Prokaryotic Cells
Bacterial Cells
The path of proteins in cells.
Ribosomes - (make proteins)
Rough Endoplasmic Reticulum –
Assists in protein synthesis by processing &
packaging proteins for storage or export.)
Golgi Apparatus - (additional
packing & destination package is given to
proteins staying or leaving)
Cell Membrane - Proteins Are Secreted
Ribosomes
Places where MRNA is
decoded to assemble
Amino Acids into protein.
Ribosomes produce
proteins for the cells that
contain them.
Animal Cell
Rough Endoplasmic
Reticulum
Assist in synthesizing
and processing
proteins. Its main job is
to separate & process
proteins that are staying
from those that are
needed by other cells.
Golgi Apparatus
Further packages
proteins for export or
storage. It also gives
destination package
for use by other cells.

Animal Cell
Cell Membrane
Controls what enters
and leaves the cell.
Defines the cell shape
in animal cells.
