What everyday object is like a endoplasmic reticulum

What everyday object compares to a smooth endoplasmic reticulum?

Why is a cell's rough endoplasmic reticulum similar to a city's industrial park? Copyright: Used with permission The endoplasmic reticulum ER is the site of synthesis of many proteins which will end up on the cell membrane, be exported from the cell or be sent to other specialised cell compartments. All endoplasmic reticulum consists of a complex interconnected series of flattened sacs or membranes. Proteins are synthesized at the ribosomes. Many of these attach to the surface of the endoplasmic reticulum, making it look 'rough' under the microscope, hence the name. As proteins are made on the ribosome, they are pushed into the sac. Here they are processed further, some are joined together with other different proteins whilst others are packaged for export or delivery within the cell. In order to make complex products, such as a car, many smaller components are needed. In many cases, the individual component factories are sited together on industrial parks as it makes sense to make all the required pieces close together and then assemble them. Similarly, some components are made and processed in a factory next door. The proximity of the factories means final products are made efficiently and can be packaged for delivery within the city or perhaps for export. The structure of a cell resembles the structure of a city - find out how with our interactive exploration. From the nucleus to the cell membrane - we explore the similarities between a cell's structure and a city. Meet the scientists who explain the link between cities and the structure of our bodies. Environmental issues are posing multiple challenges to people and ecosystems across the planet. These challenges can only be addressed effectively if the complex connections between the societal social, political, economic, cultural, and ethical and the biophysical geological, physical, ecological dimensions of environmental issues are taken seriously. This innovative, interdisciplinary degree combines the social and natural sciences to help you understand these different dimensions and why their interrelationships matter as we respond to intensifying environmental change. This certificate combines aspects of science, technology and social science to help you understand the environments in which we live and work; how our activities influence them; how they influence what we do; and how can we live sustainably within them. Environmental management can be understood as managing our relationship with the environment. For all of us, this relationship is under increasing pressure. Why is environmental management vital for our sustainability? What kind of environmental management do we need now? This online module explores the answers to questions like these by introducing ideas, approaches and techniques for environmental management at individual, organisational and community levels. Recognising that our understanding of human-environment relations is changing, this module combines conventional with innovative systems approaches to environmental management, including an approach to community participation which is taught through a series of group activities.

Endoplasmic reticulum


The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae in the RERand tubular structures in the SER. The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cellsor 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. The outer cytosolic face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis. The rough endoplasmic reticulum is especially prominent in cells such as hepatocytes. The smooth endoplasmic reticulum lacks ribosomes and functions in lipid synthesis but not metabolismthe production of steroid hormonesand detoxification. The ER was observed with light microscope by Garnier inwho coined the term "ergastoplasm". PorterAlbert Claudeand Ernest F. The general structure of the endoplasmic reticulum is a network of membranes called cisternae. These sac-like structures are held together by the cytoskeleton. The phospholipid membrane encloses the cisternal space or lumenwhich is continuous with the perinuclear space but separate from the cytosol. The functions of the endoplasmic reticulum can be summarized as the synthesis and export of proteins and membrane lipids, but varies between ER and cell type and cell function. The quantity of both rough and smooth endoplasmic reticulum in a cell can slowly interchange from one type to the other, depending on the changing metabolic activities of the cell. Transformation can include embedding of new proteins in membrane as well as structural changes. Changes in protein content may occur without noticeable structural changes. The surface of the rough endoplasmic reticulum often abbreviated RER or Rough ER also called granular endoplasmic reticulum is studded with protein-manufacturing ribosomes giving it a "rough" appearance hence its name. A ribosome only binds to the RER once a specific protein-nucleic acid complex forms in the cytosol. This special complex forms when a free ribosome begins translating the mRNA of a protein destined for the secretory pathway. The protein is processed in the ER lumen by an enzyme a signal peptidasewhich removes the signal peptide. Ribosomes at this point may be released back into the cytosol; however, non-translating ribosomes are also known to stay associated with translocons. The membrane of the rough endoplasmic reticulum forms large double-membrane sheets that are located near, and continuous with, the outer layer of the nuclear envelope. The rough endoplasmic reticulum works in concert with the Golgi complex to target new proteins to their proper destinations. The second method of transport out of the endoplasmic reticulum involves areas called membrane contact siteswhere the membranes of the endoplasmic reticulum and other organelles are held closely together, allowing the transfer of lipids and other small molecules. In most cells the smooth endoplasmic reticulum abbreviated SER is scarce. Instead there are areas where the ER is partly smooth and partly rough, this area is called the transitional ER. The transitional ER gets its name because it contains ER exit sites. These are areas where the transport vesicles that contain lipids and proteins made in the ER, detach from the ER and start moving to the Golgi apparatus. Specialized cells can have a lot of smooth endoplasmic reticulum and in these cells the smooth ER has many functions. Cells which secrete these products, such as those in the testesovariesand sebaceous glands have an abundance of smooth endoplasmic reticulum. Smooth endoplasmic reticulum is found in a variety of cell types both animal and plantand it serves different functions in each. The smooth endoplasmic reticulum also contains the enzyme glucosephosphatasewhich converts glucosephosphate to glucose, a step in gluconeogenesis. It is connected to the nuclear envelope and consists of tubules that are located near the cell periphery.

Wiki User The rough ER completes synthesis of membrane proteins and proteins that are to be exocytosed, so I suppose it would be most similar to a mixing bowl. In that case, I guess the oven would be the Golgi. Rough ER looks like a maze and smooth ER looks like a sculpture. Asked in Genetics What does the rough ER look like? The rough ER is a long coiled tube that looks like a intestine. If it is rough it has ribosomes traveling on it. Asked in Biology, Genetics How can you use endoplasmic reticulum with a house object? For rough ER, hallways. For smooth Er, medicine. The rough ER has little things called ribosomes attached to it, the smooth ER does not have anything attached like this. A rough ER is when everything goes crazy and you start getting mad and you might die. A smooth ER is when everything is calm and not crazy like a rough ER. Asked in Microbiology, Cell Biology cytology What are smooth and rough endoplasmic reticulum? Smooth ER aren't covered in ribosomes, but rough ER are. ER are like transport tubes that go through the cell. Asked in Genetics What makes the rough ER rough? And if you take off he ribosomes you get the smooth ER!!! Asked in Genetics How can you tell an rough er from a smooth er? A rough er has ribosomes while a soft er does not. Asked in Genetics What is the differentiate between the rough er and smooth er? Rough endoplasmic reticulum has ribosomes on it, these are responsible for proten synthesis. The smooth ER on the other hand does not have ribosomes.

Endoplasmic reticulum

The two regions of the ER differ in both structure and function. Smooth ER lacks attached ribosomes. Typically, the smooth ER is a tubule network and the rough ER is a series of flattened sacs. The space inside of the ER is called the lumen. Since the ER is connected with the nuclear envelope, the lumen of the ER and the space inside the nuclear envelope are part of the same compartment. The rough endoplasmic reticulum manufactures membranes and secretory proteins. The ribosomes attached to the rough ER synthesize proteins by the process of translation. In certain leukocytes white blood cellsthe rough ER produces antibodies. In pancreatic cellsthe 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. Some proteins are sent to the Golgi apparatus by special transport vesicles. After the proteins have been modified in the Golgi, they are transported to their proper destinations within the cell or exported from the cell by exocytosis. Smooth ER also serves as a transitional area for vesicles that transport ER products to various destinations. In liver cells the smooth ER produces enzymes that help to detoxify certain compounds.
