The difference in lipid and protein composition between the membranes of the endomembrane system is largely determined by
A)the physical separation of most membranes from each other.
B)the transportation of membrane among the endomembrane system by small membrane vesicles.
C)the function of the Golgi apparatus in sorting membrane components.
D)the modification of the membrane components once they reach their final destination.
E)the synthesis of lipids and proteins in each of the organelles of the endomembrane system.

Question

Quizplus · Accepted Answer

The Golgi apparatus is responsible for sorting and modifying membrane components and helps to determine the lipid and protein composition of each membrane in the endomembrane system. Other mechanisms such as vesicle transport and membrane synthesis do contribute, but the Golgi apparatus plays a central role in determining the differences between membranes.
