The two organelles that are primarily involved in making and transporting proteins in a cell are:
-
Ribosomes: These are the molecular machines that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.
-
Endoplasmic Reticulum (ER): Specifically, the rough endoplasmic reticulum (RER) is studded with ribosomes and plays a key role in the synthesis and initial folding of proteins. It also helps in transporting these proteins to other parts of the cell or to the Golgi apparatus for further processing.
Together, ribosomes and the rough ER are crucial for protein production and transport in cells.
