What can an endoplasmic reticulum be compared to?
The endoplasmic reticulum is like the highway system because the cell uses the endoplasmic reticulum to move material throughout the cell like people use highways to move throughout the country.
Is endoplasmic reticulum found in humans?
The function of the endoplasmic reticulum. The ER is known to serve multiple roles in human cells (Schwarz DS et al. One of the major functions of ER is in translation of mRNA to certain groups of proteins, including secreted proteins and integral membrane proteins, but also some cytosolic proteins.
What part of the body is like the Golgi body?
Like the Golgi apparatus, the heart packages nutrients and sends them off to the parts of the body that need it.
What is a real life example of endoplasmic reticulum?
Thee proteins on the ribosomes collect in the Endoplasmic Reticulum to help transport the proteins throughout the cell. It is responsible for protein synthesis. A real life example of the Rough Endoplasmic Reticulum would be traffic on a highway.
What does the endoplasmic reticulum do?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
Where is the endoplasmic reticulum located in the human cell?
The endoplasmic reticulum (ER) is a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells. All eukaryotic cells contain an ER.
What type of protein is in the endoplasmic reticulum?
These proteins are of two types: transmembrane proteins, which are only partly translocated across the ER membrane and become embedded in it, and water-soluble proteins, which are fully translocated across the ER membrane and are released into the ER lumen.
What human organ is the mitochondria like?
What organ system is mitochondria similar to? The mitochondria is similar to the digestive system They both break down nutrients to produce energy Page 2 What organ system is similar to lysosomes and vacuoles? Compare lysosomes and vacuoles to the excretory system.
What everyday object is like rough ER?
How would you describe the endoplasmic reticulum?
Endoplasmic reticulum is a network of membranes inside a cell through which proteins and other molecules move. Proteins are assembled at organelles called ribosomes. Smooth endoplasmic reticulum lacks ribosomes and helps synthesize and concentrate various substances needed by the cell.
Why is the endoplasmic reticulum important?
The endoplasmic reticulum (ER) serves important functions particularly in the synthesis, folding, modification, and transport of proteins. SER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane.
What is endoplasmic reticulum and its function?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. So the endoplasmic reticulum is an organelle that’s really a workhorse in producing proteins and substances needed by the rest of the cell.
What are some facts about endoplasmic reticulum?
Endoplasmic Reticulum. Endoplasmic reticulum is a network of membranes or tubes in a cell through which materials move. As an organelle in a eukaryotic cell (complex cells having nuclei and other organelles), it is involved with the production of new proteins as well as with the movement of materials throughout the cell.
What does the endoplasmic reticulum look like?
The endoplasmic reticulum looks like a system with membranes that form cavities, flat cisterns and non-lamellar, round structures.
What are analogies for endoplasmic reticulum?
The ER is like a massive shipping facility that folds, packages, and exports proteins to destinations inside and outside of the cell. Hence it can be an analogy for endoplasmic reticulum.
Why is the endoplasmic reticulum attached to nucleus?
The close association between the endoplasmic reticulum and the nucleus also enables the organelles to share information in a very efficient manner. For instance, if the endoplasmic reticulum begins to undergo functional problems and unfolded proteins accumulate within the organelle, which can be extremely hazardous to the cell, the organelle quickly sends a signal to the nucleus (as well as to the cytoplasm).
