In one method, transport proteins in the cell membrane "pick up" molecules outside the cell and carry them in, using energy. Transport proteins also carry molecules out of cells in a similar way.
ribosomes make proteins and the endoplasmic reticulum transports materials through the cell
Proteins.
On the cellular level, it is the endoplasmic reticulum which processes and transports proteins.
proteins
The Golgi body
The vesicles because it contains and transports various substances such as protein
Endoplasmic Reticulum (probably rough ER).
Golgi Apparatus
because
Ribosomes are the protein factories of the body and golgi bodies are known to trasport the proteins in the body.
Rough Endoplasmic Reticulum synthesizes proteins and sends them to the Golgi Apparatus for modification and packaging.
