Where are the ribosomes that translate proteins to be secreted from the cell?
Answer:
Proteins that are meant to be secreted from the cell are translated by ribosomes associated with the endoplasmic reticulum (ER). These ribosomes are called “membrane-bound ribosomes” or “bound ribosomes.” The ribosomes attached to the ER enable the newly synthesized proteins to be translocated directly into the endoplasmic reticulum as they are being translated. Once inside the ER, these proteins undergo further processing, folding, and may be modified before they are transported to their final destination within or outside the cell. This mechanism ensures that the proteins destined for secretion are properly synthesized and processed before being released from the cell.
