The Endoplasmic Reticulum
How the Endoplasmic Reticulum are work(and Explain)
the endoplasmic reticulum or Er is netwrok of imrecellular membrances connected to the nuclear envelope which surrounds the nucleus the name endoplasmic reticulum is very descriptive endo means'' within'' plasm refers to the cytoplasm and a reticulum is a network the ER has
four major functions
four major functions
- synthesis. Specialized regions of the ER synthesize proteins, carbohydrates, and lipids.
- storage. the ER can store synthesized molecules or materials absorbed from the cytosol without affecting other cellular opllular operations.
- Transport. materials can travel from place to place in the ER.
- Detoxification. Drug or toxins can be absorbed by the ER and neutralized by enzymes within it.
- Smooth endoplasmic Reticulum the term ''smooth'' refers to the fact that no ribosomes are associated with the smooth endoplasmic reticulum. the SER has the foloowing functions all associated with the synthesis of lopids and carbohydrates.
- Rough Endoplasmic Reticulum funtions as a combination workshop and shipping depot. it is where many newly synthesized proteins are chemically modified and packaged for export to their next destination.
Why endoplasmic are important?
- they serve as structural support to the cell.
- they help in transporting materials through the cell.
- they aid in translation of RNA due to the presense of many ribosome on its surface.
- they help in the modification of proteins to form glycoproteins.
- Endoplasmic Reticulum produces proteins & lipids.
