Rer diagram

The Endoplasmic Reticulum ER is a complex system of tubes found solely in the rer diagram of eukaryotic cells. We can learn about its structure with the help of a diagram of the endoplasmic reticulum easy way.

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.

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 ER is a part of a transportation system of the eukaryotic cell , and has many other important functions such as protein folding. It is a type of organelle made up of two subunits — rough endoplasmic reticulum RER , and smooth endoplasmic reticulum SER. The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae in the RER , and 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 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. RER is found mainly toward the nucleus of cell and SER towards the cell membrane or plasma membrane of cell. The outer cytosolic face of the RER is studded with ribosomes that are the sites of protein synthesis. The RER is especially prominent in cells such as hepatocytes.

The endoplasmic reticulum ER is a network of membrane-enclosed tubules and sacs cisternae that extends from the nuclear membrane throughout the cytoplasm. AhdOmer June 2, , pm 1. Diagram of the Endoplasmic Reticulum. The diagram of Endoplasmic Reticulum consists of many structures that helps it in the different functions. The diagram shows a section of rough endoplasmic reticulum RER. Which answer correctly identifies the substances associated with structures 1 and 2? It connects to the plasma membrane, the membrane surrounding the nucleus, and the membranes of the Golgi apparatus. With those 2 labels established, how do we begin answering this question?

As scientists learn more, the endoplasmic reticulum diagram will continue to help us discover new methods to applying this information in medicine and other fields.

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

You now know that label 1 is a ribosome, which is the main cellular machinery involved in the process of translation or the production of proteins. Albert June 19, , am 2. The endoplasmic reticulum contains few components like:. Work Experiences. The endoplasmic reticulum ER is a complex network of tubes and compartments located within cells. Thus, it makes sense that the polypeptide chain that was just produced to go to the lumen for the RER to act on it. Suggest changes. Trending in News. Interview Experiences.
