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.

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. These flat discs of phospholipid membrane appear stacked together when looking at a cross section of the endoplasmic reticulum under a powerful microscope.

The endoplasmic reticulum is the major site of synthesis in the cell. It is a system of flattened sacs cisternae that are continuous with the outer nuclear envelope. Its physiological function has a very close association with that of the Golgi apparatus and together, they form the secretory pathway of the cell. The endoplasmic reticulum is classified as either rough or smooth, with minor variations in size and function in specialised tissue. In this article, we will look at the structure and function of the rough and smooth endoplasmic reticulum, and consider some clinical relevance. The rough endoplasmic reticulum RER takes its name from the many ribosomes attached to the cytoplasmic surface. The RER takes developing proteins from the cytosol and continues their development prior to completion in the golgi apparatus. Proteins that move across the membrane of the RER undergo a series of post-translational modifications , including the addition of signal sequences to target them to the correct part of the cell. Cells that produce many secretory proteins will have will extensive RER and mitochondria. Part of the modification process involves the folding of developing proteins.

The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.

The diagram of Endoplasmic Reticulum consists of many structures that helps it in the different functions. There are two types of endoplasmic reticulum: Rough endoplasmic reticulum and Smooth endoplasmic reticulum. Admission Experiences. Like Article. Thus, it now makes sense that only choice B is correct. The diagram of the endoplasmic reticulum with labeling is given below:. What is the Endoplasmic Reticulum?
