katie-ann Posted October 12, 2005 Posted October 12, 2005 we had an assignment in biology and im a bit stuck the cell organelles are structually and functionally interrelated discuss this statement in relation to to the golgi body mitochondrion lysosome and rER......i have submitted my answer once and had it returned i have stated the functions and how they were related to one another im wondering if anyone else has anything more to add i know you cant see what i have written on my assignment im not sure what is meant by interrelated means in this context thanks to any-one who has an answer for me
Bio-Hazard Posted October 13, 2005 Posted October 13, 2005 what did you submit? Think you could give a bit more detail?
Karnage Posted October 13, 2005 Posted October 13, 2005 Katie Ann. From what I know, the rough endoplasmic reticulum, the golgi apparatus, lysosomes are all part of what we call the endomembrane system. They are all interrelated. This means that all these organelles are part of a system. Proteins destined for secretion are made on ribosomes bound to the rough ER. The proteins move through the endomembrane system and are dispatched from the Golgi apparatus in transport vesicles that move through the cytoplasm and then fuse with the plasma membrane, releasing the protein to the outside of the cell. Examples of secretory proteins are collagen, insulin, and digestive enzymes of the stomach and intestine. (In a similar way, proteins destined for a particular cell organelle move to the organelle in transport vesicles that deposit their contents in the organelle by membrane fusion.) Here is another explanation: Proteins synthesized in the rough ER travel inside vesicles to the Golgi apparatus, which detects chemical tags on these proteins, alters their structure, then releases them in other vesicles targeted for different destinations.
