Learn Biology: Cells—Endoplasmic Reticulum

Learn Pilates (but save $$$): biology expert Mary Poffenroth teaches you about the endoplasmic reticulum in a cell.Endoplasmic Reticulum---------------------------------------------------------------------Endoplasmic reticulum is one of the main manufacturing organelles in a cell. Think of it as a factory producing proteins and lipids.?There are two parts of the endoplasmic reticulum - the rough endoplasmic reticulum and the smooth endoplasmic reticulum.c?Rough Endoplasmic Reticulum---------------------------------------------------------------------The rough portion of the endoplasmic reticulum is studded with?ribosomes?that are responsible for making proteins and shipping them to the rest of the cell via the Golgi apparatus. The rough endoplasmic reticulum looks like sheets of bumpy membranes.c?Smooth Endoplasmic Reticulum---------------------------------------------------------------------The smooth portion has no ribosomes and is used to make lipids, like steroids; it also helps liver cells?detoxify?circulating drugs from the body. It also stores ions that the cell will use at a later time. The smooth endoplasmic reticulum looks like soft tubing.c?c??Read more by visiting our page at:
