Document Summary
The endomembrane system contains everything that become microsomes and vesicles. Smooth endoplasmic reticulum (ser: very similar to the rer, no ribosomes, also interconnected. 2-15-17: after a bit, they would remove the radioactive amino acid and let the (cid:272)ell(cid:859)s gro(cid:449) (cid:449)ith (cid:272)old a(cid:373)i(cid:374)o a(cid:272)ids, then they used microscopy. If you wait a little longer, you will have some in the rer and some in the golgi.

Internal membranes (for the most part), functionally related, all likely evolved from enfolding of the plasma membrane. 2-15-17: ca++ floods the cytoplasm, binds to those proteins, undergoes conformational change, vesicles fuse with the membrane, and out go all the digestive enzymes into the duodenum. Overview of the organelles involved in the endomembrane system:
