Endoplasmic Reticulum & Ribosomes By: T’keyah JonathanMaria

Endoplasmic Reticulum Ribosomes  The endoplasmic reticulum is a eukaryotic organelle that forms an interconnected network of tubules and vesicles within cells.  These structures are responsible for several specialized functions: protein translation and the folding and transport of proteins to be used in the cell membrane.

Endoplasmic Reticulum Ribosomes  The surface of the rough endoplasmic reticulum is studded with protein- manufacturing ribosomes giving it a "rough" appearance.  The RER is not always studded with these ribosomes, however initially, the RER appears smooth due to a lack of resident ribosomes.

Endoplasmic Reticulum Ribosome’s  Ribosomes transport to the cytoplasm through the nuclear envelope.  Ribosomes are not bound by a membrane and they are simple structures made of RNA and protein.  Ribosomes help to make proteins that perform tasks within the cytoplasm itself.

Endoplasmic Reticulum  This is a picture of the endoplasmic reticulum. It also shows the rough endoplasmic reticulum and the smooth endoplasmic reticulum.

Ribosomes  This is a picture of ribosomes in a cell. It shows the nuclear envelope, the nuclear pore, the Golgi apparatus and many other things.
