The endomembrane system is very important for synthesizing, processing, and movement of lipids and proteins in the cell.
The smooth ER function is mainly used for lipid synthesizing and processing, while the rough ER function is for protein synthesizing
hope this helps
I believe that you're question is referring to homeostasis
I would have to say Proteins, lipids, and carbohydrates. Carbohydrates being the first energy source, lipids second and lasting the longest, and proteins the third and final source. although you did not give the full question, so i do not know if i can be completely sure.
