What is a endoplasmic reticulum in simple words?
Endoplasmic reticulum is a collection of tubes that make, package, and transport proteins and fats. Rough endoplasmic reticulum has protein-making ribosomes on its surface, so it helps make and process proteins. Smooth endoplasmic reticulum helps make and process lipids and helps detoxify drugs and alcohol.
What is a endoplasmic reticulum quizlet?
Definition of Endoplasmic Reticulum. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in plant and animal cells. Difference between rough and smooth endoplasmic reticulum.
What is the main 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.
What is another word for the endoplasmic reticulum?
What is another word for endoplasmic reticulum?
| endoplasmatic reticulum | ergastoplasm |
|---|---|
| rough ER | sarcoplasmic reticulum |
| smooth ER |
What is endoplasmic reticulum structure?
The endoplasmic reticulum is the largest single structure in eukaryotic cells. It consists of a range of interconnected shapes, including sheets and tubules, and comprises a lumen enclosed by a membrane that is continuous with the membrane that surrounds the nucleus of the cell (Figure 1).
Which of the following describes the structure of the endoplasmic reticulum?
Explanation: Structure of the endoplasmic reticulum is a network of membranes. These network structures are interwoven together and form the cytoskeleton. The phospholipid nature of membrane encloses the space or lumen.
Which of the following is a function of endoplasmic reticulum quizlet?
What is the function of the Endoplasmic Reticulum? The Endoplasmic Reticulum transports nutrients from one part of the cell to the other.
What is endoplasmic reticulum describe its structure?
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. In animal cells, the ER usually constitutes more than half of the membranous content of the cell.
What is endoplasmic reticulum made of?
ROUGH ENDOPLASMIC RETICULUM This is an extensive organelle composed of greatly convoluted but flattish sealed sacs, which are contiguous with the nuclear membrane. It is called ‘rough’ endoplasmic reticulum because it is studded on its outer surface (the surface in contact with the cytosol) with ribosomes.
What is the structure of endoplasmic reticulum?
Is endoplasmic reticulum double membrane?
Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell. Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.
What are types of endoplasmic reticulum describe their structure and function?
The two types of endoplasmic reticulum are : Rough Endoplasmic Reticulum: Their main function is produce proteins in the cells and ribosomes are attached to their surface. Smooth Endoplasmic Reticulum: Their main function is to produce lipids and also detoxify toxins in the body in the liver and kidney cells.
What is the endoplasmic reticulum?
What is the endoplasmic reticulum? 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. In animal cells, the ER usually constitutes more than half of the membranous content of the cell.
What does the rough endoplasmic reticulum do in white blood cells?
Rough Endoplasmic Reticulum. In certain leukocytes (white blood cells), the rough ER produces antibodies. In pancreatic cells, the rough ER produces insulin. The rough and smooth ER are usually interconnected and the proteins and membranes made by the rough ER move into the smooth ER to be transferred to other locations.
Why is the endoplasmic reticulum not found in red blood cells?
The endoplasmic reticulum is not found in red blood cells, or spermatozoa . The two types of ER share many of the same proteins and engage in certain common activities such as the synthesis of certain lipids and cholesterol. Different types of cells contain different ratios of the two types of ER depending on the activities of the cell.
What is the function of the smooth endoplasmic reticulum Quizlet?
The smooth endoplasmic reticulum (abbreviated SER) has functions in several metabolic processes. It synthesizes lipids, phospholipids, and steroids. Cells which secrete these products, such as those in the testes, ovaries, and sebaceous glands have an abundance of smooth endoplasmic reticulum.
