With such a long name, the endoplasmic reticulum had better be important! And it is — it's a multi-tasking organelle that synthesizes fats and proteins. The endoplasmic reticulum works with the Golgi body and ribosomes to keep cells functioning smoothly. Short and sweet discussion with colorful diagrams of the smooth and rough ER.
- Role of the Ribosome
Those funny little bumps all over the rough ER aren't polka dots or measles — they're ribosomes. Ribosomes are responsible for constructing proteins, the building blocks of enzymes and hormones. Proteins also play an essential role in building and repairing muscles. Trace the involvement of ribosomes in the route from DNA transcription to protein formation on this University of Texas Medical Branch website.
- Classified Information!
Taxonomy was taxing until ribosome research rolled around. Ribosomes help to clarify the issue of organism classification. Scientists once based classification on appearance. But what about microorganisms and bacteria that can't be grown and studied in the lab? The Whyfiles explains how ribosomal DNA has helped scientists restructure the hierarchy of the biosphere.
- The Fat Dance
Don't miss the "Fat Dance"! A challenging, very cool, animation-intense webpage on the structure and function of many cell organelles, including protein transcription and hormone receptors at work. Scroll along the entire webpage to view the informative animations and pictures. The Fat Dance is at the bottom of the page; it shows how various parts of the cell package materials.
- Cell Anatomy: Endoplasmic Reticulum
Ever wonder how a factory's machines are made? By other machines, of course. In the cell factory, the endoplasmic reticulum synthesizes proteins that are used to make other cellular machinery known as organelles. This webpage, part of Cellupedia, a thinkquest-hosted website, introduces the structure and function of the endoplasmic reticulum and links to further information on protein synthesis and ribosome function.
