What does the endomembrane system do?

The endomembrane system is a complex network of membranes within eukaryotic cells that plays a crucial role in various cellular processes. The primary function of this system is to process proteins and detoxify poisons. This includes the endoplasmic reticulum, which is involved in the synthesis of proteins and lipids; the Golgi apparatus, which modifies, sorts, and packages proteins for secretion or use within the cell; and lysosomes, which digest macromolecules and break down waste materials and cellular debris.

This system is especially important in maintaining cellular homeostasis and ensuring that proteins are correctly folded and functional before they are distributed throughout the cell or secreted outside. In addition, organelles like the smooth endoplasmic reticulum are vital for detoxification processes, as they can modify and neutralize various toxins and drugs that enter the cell.

The other choices describe functions that are not associated with the endomembrane system. Cell movement pertains more to structures like the cytoskeleton. Storing genetic information is primarily the role of the nucleus, and energy production is the function of organelles like mitochondria in cellular respiration. These distinctions help underline the specific roles of the endomembrane system in cellular function.
