Proteins That Will Be Exported from the Cell are Produced

Question

Proteins that will be exported from the cell are produced by
A) ribosomes inside mitochondria
B) ribosomes found in lysosomes
C) ribosomes attached to rough endoplasmic reticulum
D) ribosomes attached to smooth endoplasmic reticulum

Accepted Answer

Proteins destined for export from the cell are synthesized by ribosomes attached to the rough endoplasmic reticulum (RER). The RER is characterized by its rough appearance due to the presence of ribosomes on its surface, and it plays a crucial role in the synthesis and processing of proteins to be secreted or incorporated into the cell membrane.
