What is endoplasmic reticulum best described as?

What is endoplasmic reticulum best described as?

Endoplasmic reticulum is best described as a. Network of interconnected membranes. Vesicles are formed from. Cell membrane.

What is endoplasmic reticulum function?

Functions. The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus. Rough endoplasmic reticulum is also involved in protein synthesis.

What best describes rough endoplasmic reticulum?

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 function of endoplasmic reticulum rough?

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. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

What is the structure of the rough ER?

The rough endoplasmic reticulum is largely made of sheets – a two-dimensional array of flattened sacs that extend across the cytoplasm. In addition to ribosomes, these membranes contain an important protein complex called the translocon, which is necessary for protein translation within the rough ER.

What is endoplasmic reticulum give its example?

The continuous extensions of outer membrane of nucleus into the cytoplasm is called endoplasmic reticulum. It is of two types: smooth endoplasmic reticulum and rough endoplasmic reticulum. In animal cells, lipid like steroidal hormones are synthesised in smooth endoplasmic reticulum.

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 are the characteristics of the endoplasmic reticulum?

The endoplasmic reticulum (ER) is a network of flattened sacs and branching tubules that extends throughout the cytoplasm in plant and animal cells. These sacs and tubules are all interconnected by a single continuous membrane so that the organelle has only one large, highly convoluted and complexly arranged lumen (internal space).

What are some examples of the endoplasmic reticulum?

The endoplasmic reticulum is defined as a series of folded membranes in the cells which are associated with protein synthesis, storage and the movement of cellular materials. An example of the endoplasmic reticulum is the place that steroids are stored in the cells for later use.

Which are the types of the endoplasmic reticulum?

Endoplasmic Reticulum : Types, Structure and Functions Physical Structure of Endoplasmic Reticulum. Tubular structures or tubules. Types of Endoplasmic Reticulum. There are two types of Endoplasmic reticulum such as Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER). Functions of Endoplasmic Reticulum. It forms the skeletal frame work of the cell.
