The internal space of the endoplasmic reticulum is called the cisternal space, or lumen, which is part of the "rough endoplasmic reticulum." The lumen is the staging area where the final modifications of protein synthesis take place, and its quality is analysed before releasing it for transportation to it's intended destination.

What body part is similar to the endoplasmic reticulum?
The endoplasmic reticulum is located inside the cells in people's bodies. The endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles.
What are the cytoplasmic space in eukaryotic cells is occupied by many diverse membrane-bound structures with specific cellular functions?
The cytoplasmic space in eukaryotic cells is occupied by organelles, such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. These membrane-bound structures carry out specific functions within the cell, such as energy production (mitochondria), protein synthesis and transport (endoplasmic reticulum and Golgi apparatus), waste removal (lysosomes), and lipid metabolism (peroxisomes).
What substance fills the space between the plasma membrane and the nuclear membrane?
The substance that fills the space between the plasma membrane and the nuclear membrane is called cytoplasm. Cytoplasm contains various organelles, such as mitochondria and endoplasmic reticulum, and plays a crucial role in cellular functions like metabolism and transport of molecules within the cell.
What is endoplasim reticulum?
the endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles. The ER contains a great amount of folds - but the membrane forms a single sheet enclosing a single closed sac. This internal space is called the ER lumen. The ER is additionally responsible for moving proteins and other carbohydrates to the Golgi apparatus, to theplasma membrane, to the lysosomes, or wherever else needed. There are two types of ER - rough, which is coated with ribosomes, and smooth, which isn't. Rough ER is the site of protein synthesis. The smooth ER is where the vesicles carrying newly synthesized proteins (from the rough ER) are budded off.
What occupies the cytoplasmic space in eukaryotic cells?
In eukaryotic cells, the cytoplasmic space is occupied by organelles like the endoplasmic reticulum, Golgi apparatus, mitochondria, and ribosomes. It also contains cytoskeleton elements, cytosolic proteins, ions, nutrients, and other molecules necessary for cellular functions.
What is a function of a endoplasmic reticulum?
The endoplasmic reticulum is a network of membrane- covered channels that look like a fold of a fan or accordion. Being folded means the endoplasmic reticulum has a large surfaced area in a small space.
What is the structure of the reticulum?
Endoplasmic reticulum has network of cisternae. Cisterna is phospholipid membrane that encloses a space (lumen) from cytosol. Cytosol contains water and macromolecules. Cisternae are held together by cytoskeleton.Endoplasmic reticulum containing ribosomes (small spherical organelles) on its membrane is called rough endoplasmic reticulum.
The endoplasmic reticulum is an extension of what?
The endoplasmic reticulum (ER) is thought to be an extension of the nuclear membrane. This structure is seen to connect the nuclear membrane to the cell membrane. When viewed under high magnification, this organelle is seen to encompass the entire cytoplasmic space between the nucleus and cytoplasm.

What is the job of an endoplasmic reticulum?

How are the Golgi body and endoplasmic reticulum different?
Well...The primary function of the Golgi apparatus is to process and package macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is particularly important in the processing of proteins for secretion. The Golgi apparatus forms a part of the cellular endomembrane system.And of courseEndoplasmic reticulum is a network of tubules, vesicles and sacs that are interconnected. They may serve specialized functions in the cell including protein synthesis, sequestration of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins. The first part of this presentation will focus on rough endoplasmic reticulum which gets its name from the presence of ribosomes on its surface.The endoplasmic reticulum (ER) is repsonible for the production of the protein and lipid components of most of the cell's organelles.

Calcium ions that act as second messengers are stored in?
Calcium ions that act as second messengers are typically stored in the endoplasmic reticulum or the extracellular space. When a signaling event triggers their release, they can quickly enter the cytoplasm to transmit the signal.
