What is a endoplasmic reticulum compared to in real life?
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.
What is an example of rough endoplasmic reticulum?
Therefore, rough ER is prominent in liver cells that secrete serum albumin, cells of the digestive system that secrete enzymes, endocrine cells that synthesize and secrete protein hormones (such as insulin) and in cells that create the proteins of the extracellular matrix.
What would be a 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.
What is the description of rough ER?
Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins.
What is the importance of endoplasmic reticulum?
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.
What are diseases caused by endoplasmic reticulum?
Endoplasmic reticulum (ER) dysfunction might have an important part to play in a range of neurological disorders, including cerebral ischaemia, sleep apnoea, Alzheimer’s disease , multiple sclerosis, amyotrophic lateral sclerosis, the prion diseases , and familial encephalopathy with neuroserpin inclusion bodies.
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.
Is the endoplasmic reticulum an animal or plant or both?
Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.
Is endoplasmic reticulum always attached to nuclear membrane?
Yes, the endoplasmic reticulum is always attached to the nuclear membrane. ER is a part of the cytoplasmic vesicular system which also consists of nuclear envelope, lysosomes, endosomes and Golgi complex. ER is a continuous system, connected on one side to nuclear envelope and on the other side to the cell membrane.
