Describe the importance of the Endomembrane System in the cell in detail..

The endomembrane system permits various functions of the eukaryotic cell to be compartmentalized (e.g., protein degradation occurs in the lysosome), allowing a higher degree of cell specialization. The system relies on dynamic interactions between different compartments, facilitated by vesicle trafficking between them.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
