Which of the following is true about the sorting pathway for proteins destined for incorporation into lysosomes or the plasma membrane of eukaryotic cells?

Question

Quizplus · Accepted Answer

The sorting pathway for proteins destined for lysosomes or the plasma membrane involves the binding of the signal recognition particle (SRP) to the signal peptide on the polypeptide chain soon after it appears outside the ribosome. This delays further elongation of the polypeptide chain and directs the ribosome to the endoplasmic reticulum (ER), where the polypeptide is translocated into the lumen. The signal peptide is then cleaved off by signal peptidase, and the newly synthesized protein can be further processed and sorted to its final destination.
