Rer diagram

The Endoplasmic Reticulum ER is a complex system of tubes found solely in the cytoplasm of eukaryotic cells, rer diagram.

Before we get into rationalizing the answer, let us be oriented with what the diagram is labeled with:. AhdOmer June 2, , pm 1. The diagram shows a section of rough endoplasmic reticulum RER. Which answer correctly identifies the substances associated with structures 1 and 2? Albert June 19, , am 2. The answer to this question is choice B. Before we get into rationalizing the answer, let us be oriented with what the diagram is labeled with: Label 1: The question tells you that this diagram is a rough endoplasmic reticulum.

The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins. The endoplasmic reticulum ER is a series of interconnected membranous sacs and tubules that collectively modifies proteins and synthesizes lipids. The hollow portion of the ER tubules is called the lumen or cisternal space. The membrane of the ER, which is a phospholipid bilayer embedded with proteins, is continuous with the nuclear envelope. Rough Endoplasmic Reticulum : This transmission electron micrograph shows the rough endoplasmic reticulum and other organelles in a pancreatic cell. The rough endoplasmic reticulum RER is so named because the ribosomes attached to its cytoplasmic surface give it a studded appearance when viewed through an electron microscope.

One of the simplest ways to understand the structures and functions of the organelles housed within a cell — and cell biology as a whole — is to compare them with real world things. For example, it makes sense to describe the Golgi apparatus as a packing plant or post office because its role is to receive, modify, sort and ship out cell cargo. This organelle factory builds the biomolecules required for all life processes. These include proteins and lipids. You probably already know how important membranes are for eukaryotic cells ; the endoplasmic reticulum, which includes both the rough endoplasmic reticulum and smooth endoplasmic reticulum , takes up over half of the membrane real estate in animal cells. It would be hard to exaggerate just how important this membranous, biomolecule-building organelle is to the cell. This unique structure ensures that the endoplasmic reticulum can perform its important roles within the cell. The endoplasmic reticulum is best understood as a long phospholipid membrane folded back on itself to create its characteristic maze-like structure. This folded phospholipid membrane forms bends called cisternae.

Diagrams of the Endoplasmic Reticulum class 8 help us grasp its functions and importantance for cell health. The diagram of Endoplasmic Reticulum consists of many structures that helps it in the different functions. Work Experiences. With that being said, what now, could label 2 signify? Label 2: This label is pointing within the organelle itself or the lumen, which is an important piece of information when trying to answer this question. Skip to content. It is an important element of the cell that performs a variety of functions. If you recall, the RER is involved in very important post-translational modification for various functions! Create Improvement. Save Article.

The endoplasmic reticulum is the major site of synthesis in the cell.

There are two types of endoplasmic reticulum: Rough endoplasmic reticulum and Smooth endoplasmic reticulum. This can be supported with the fact that it is different from FREE ribosomes, where the protein synthesized by free ribosomes can freely move around within the cell, whereas the polypeptides produced by ribosomes ATTACHED to the endoplasmic reticulum is NOT free to move around, and is subject to post-translational modification before it is sent out of the cell. AhdOmer June 2, , pm 1. It is absent in prokaryotes cells but found in all eukaryotic cells, except for mammalian red blood cells and germinal cells. Explore offer now. Skip to content. The answer to this question is choice B. Label 2: This label is pointing within the organelle itself or the lumen, which is an important piece of information when trying to answer this question. The smooth endoplasmic reticulum SER lacks ribosomes and is involved in lipid synthesis, metabolism, and detoxification. The endoplasmic reticulum ER is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding, calcium storage and lipid metabolism.
