Write a paragraph describing the function of the endomembrane system? Include these terms: DNA, RNA, Ribosome, Endoplasmic Reticulum, Golgi Apparatus, plasma membrane, secretory vesicle, free ribosome, bound ribosome, protein.

Please find the function of the endomembrane system below.

Explanation:

The endomembrane system is a system of membranous organelles in eukaryotic cells which plays the collective role of synthesis, modification, packaging and transportation of lipids and proteins within the cell. The organelles involved are endoplasmic reticulum, Golgi apparatus, vesicles and plasma membrane.

DNA, which is the genetic material in living cells encodes genetic information. The information in DNA is transcribed in the nucleus into a RNA molecule, which is then translated in the ribosomes (organelle for protein synthesis) into PROTEINS. Ribosomes can either be free or membrane-bound depending on whether it produces proteins that are used in the cell or are exported out of the cell respectively. However, ribosomes are attached to the surfaces of endoplasmic reticulum making them called ROUGH ENDOPLASMIC RETICULUM. This makes rough endoplasmic reticulum associated with protein production/synthesis.

The synthesized proteins is then packaged and modified in the GOLGI APPARATUS, after which it is transported by SECRETORY VESICLES that transports it to the PLASMA MEMBRANE for exocytosis.
