Smooth Endoplasmic Reticulum: best hiking experience

 If your looking for a vigorous hike to do alone or with the kids, you've come to the right place. The Smooth Endoplasmic Reticulum is a generally moderate terrain, free of ribosomes; the SER loops back and forth between the nucleus and the cell membrane, though if continued it will travel throughout the rest of the cell's property. This is a trail for intermediate to advanced hikers, do to the thickness of the surrounding cytoplasm, which may be difficult for beginner hikers. Also, the production of lipid molecules can also be burdensome to beginners.
