Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Of the following, which is probably the most common route for membrane flow in the endomembrane system?
A
Golgi
B
tonoplast
C
nuclear envelope
D
rough ER
E
ER
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’.

Detailed explanation-2: -The secretory pathway refers to the endoplasmic reticulum, Golgi apparatus and the vesicles that travel in between them as well as the cell membrane and lysosomes. It’s named ‘secretory’ for being the pathway by which the cell secretes proteins into the extracellular environment.

Detailed explanation-3: -Conventional protein secretion is mediated by the endomembrane system. Secreted proteins are inserted into the endomembrane system through a N-terminal signal peptide and follow the endoplasmic reticulum to the Golgi trafficking pathway en route to the plasma membrane or the extracellular apoplastic space.
