A protein being synthesized by a cell for export would follow which pathway in the cell?
A) ribosome to cell membrane
B) ribosome to endoplic reticulum to Golgi apparatus to cell membrane
C) ribosome to Golgi apparatus to endoplic reticulum to cell membrane
D) ribosome to lysosome to endoplic reticulum to Golgi apparatus to cell membrane

Question

Quizplus · Accepted Answer

Proteins targeted for export are synthesized by ribosomes attached to the rough endoplasmic reticulum (ER), transported through the ER lumen to the Golgi apparatus, and then further modified and packaged before being transported to the cell membrane for secretion. This is known as the secretory pathway. Therefore, only option B correctly depicts the secretory pathway in the cell.
