Q
  • has attached ribosomes
  • Receives the proteins that are synthesized by the ribosomes- processes these proteins before passing them to the Golgi bodies in the form of transfer vesicles

Q
  • has no ribosomes attached
  • Site of lipid synthesis, fats, and cholesterols. Also involved in the metabolism of carbohydrates, detoxification, and transportation of lipids and fatty acids.

Q

Consists of several layers of membrane-bound, smooth-surfaced and flattened tubes (cisternae) that are stacked on top of each other in a semicircular manner.
* Lateral ends exhibit dilations filled with fluid.
* Works by processing, concentrating, sorting and packaging of proteins that are sent by the rER.
* Proteins are then released into the cytoplasmic matrix in a form of secretory vesicles.

Q

Also called microtubule organizing center (mtoc)
* Dense, spherical area in the cytoplasm.
* Consist of pairs of centrioles
* Organelles that produce microtubules that fo* Its walls are made up of 9 groups of microtubules. Each group is called triplets (3 microtubules)
