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

Question

Quizplus · Accepted Answer

A protein synthesized for export would first be directed to the endoplasmic reticulum (ER) by a ribosome. The protein would then undergo processing and modification in the ER before being packaged into vesicles and transported to the Golgi apparatus. In the Golgi apparatus, further processing and modification of the protein occur before it is sorted and packaged into vesicles for export to the cell membrane. Therefore, the correct pathway would be ribosome to endoplasmic reticulum to Golgi apparatus to cell membrane (option B).
