What is the main function of endoplasmic reticulum?

What is the main function of endoplasmic reticulum?

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.

What does the endoplasmic do in a cell?

endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .

What is the function of the endoplasmic reticulum in a cell quizlet?

endoplasmic reticulum- A system of membranes that is found in a cell’s cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.

What is the function of endoplasmic reticulum or ER What is the function of mitochondria?

Answer: Mitochondria is the powerhouse of cell as it provides energy in the form of ATP molecules. Endoplasmic reticulum modifies,packages and synthesizes proteins.

What is the structure and function 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 is endoplasmic reticulum in simple words?

A network of sac-like structures and tubes in the cytoplasm (gel-like fluid) of a cell. Proteins and other molecules move through the endoplasmic reticulum. The outer surface of the endoplasmic reticulum can be smooth or rough. The endoplasmic reticulum is a cell organelle.

What is the structure and function of the rough ER quizlet?

Called the rough endoplasmic reticulum because it has ribosomes on the surface. It is found in both plant and animal cells. It is found in both plant and animal cells. Function: holds all organelles in place.

What is the structure and function of the smooth ER quizlet?

One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids, an essential component of a cell’s outer membrane, and steroids.

What are the three functions of smooth endoplasmic reticulum?

Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.

What is the structure and function of the endoplasmic reticulum?

The endoplasmic reticulum (ER) is the largest membrane-bound organelle in eukaryotic cells and performs a variety of essential cellular functions, including protein synthesis and processing, lipid synthesis, and calcium (Ca2+) storage and release.

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 smooth endoplasmic reticulum do?

The smooth endoplasmic reticulum performs a number of important metabolic functions within the cell. The exact function changes depending on the specific cell type. When not metabolizing a compound, the smooth endoplasmic reticulum acts as a storage site until metabolism begins again.

What does endoplasmic reticulum look like?

The endoplasmic reticulum looks like a system with membranes that form cavities, flat cisterns and non-lamellar, round structures.

Where is the rough endoplasmic reticulum located?

Rough Endoplasmic Reticulum (Rough ER) Location: The Rough ER is located in the cytoplasm of the cell and is attached to the outside of the nuclear envelope. Structure: The Rough ER is a complex network of tubes and sacks enclosed by a membrane.
