Mahalo 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 Rough Endoplasmic Reticulum
The rough portion of the endoplasmic reticulum is studded with Smooth Endoplasmic Reticulum
The smooth portion has no ribosomes and is used to make lipids, like steroids; it also helps liver cells References

Mary Poffenroth
Mary Poffenroth is an adjunct professor of biology at San Jose State University. She holds a master's degree in biological sciences from same. Apart from hosting Mahalo videos, Poffenroth writes, produces and hosts her own short films. One such film received two honorable mentions at the 2010 International Wildlife Film Festival and her videos also appear in the 2011 edition of the Wiley International college textbook. "I want to make deceptively educational videos," she says, "that will both entertain and inspire."
