Endoplasmic reticulum (er) is a complex network of membranes, that is found in the form tubules, and compressed, sac-like structures called cisternae the internal space of the organelle, called cisternal space, is interconnected and fluid-filled.

The structure of the endoplasmic reticulum is classified in two types, which are rough er and smooth er the rough er is studded with ribosomes the rough endoplasmic reticulum is predominantly found in hepatocytes where protein synthesis occurs actively the smooth endoplasmic reticulum is a smooth network without the ribosomes. Smooth er was first described as agranular reticulum with smooth membrane and ribosome free local differentiation of er apparatus which was in irregular communication with er by vesicular transport [1,2]. Today, scientists know that the endomembrane system includes the endoplasmic reticulum (er), golgi apparatus, and lysosomes nature reviews molecular cell biology 10, 360-364 (2009) all . It works closely with the golgi apparatus, ribososmes, mrna, and trna structurally, the endoplasmic reticulum is a network of membranes found throughout the cell and connected to the nucleus the membranes are slightly different from cell to cell and a cell’s function determines the size and structure of the er.

In cell: the smooth endoplasmic reticulum the functions of the ser, a meshwork of fine tubular membrane vesicles, vary considerably from cell to cell one important role is the synthesis of phospholipids and cholesterol, which are major components of the plasma and internal membranes. Biology unit 1 study guide we will write a custom essay sample on biology unit 1 study chloroplast, smooth/rough endoplasmic reticulum, golgi bodies .

The endoplasmic reticulum (er) is an organelle (a specialized cell part) that appears in all eukaryotic cells (eukaryotic organisms include all living things e. Let us take a look at the structure of endoplasmic reticulum, before we talk about its functions about endoplasmic reticulum to understand what is the endoplasmic reticulum, let's break this biology term into two parts. Organelles include mitochondria, the endoplasmic reticulum the golgi apparatus and lysosomes” [1] the nucleus is usually the largest structure inside the cell which contains chromosomes which contains deoxyribonucleic acid (dna), this is the genetic coding material which determines difference characteristics. The factory of the cell is an organelle called the rough endoplasmic reticulum, the rough er sends the protein to an organelle called the golgi apparatus at the golgi, the protein is then .

Endoplasmic reticulum (er), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins. The endoplasmic reticulum (er) is a system of membrane-enclosed sacs and tubules in the cell their lumens are probably all interconnected, and their membranes are continuous with the outer membrane. Free practice questions for sat ii biology m - endoplasmic reticulum and golgi body includes full solutions and score reporting. Ribosomes are small spherical organelles, composed of two subunits, which can be found on the rough endoplasmic reticulum (and also in the cytoplasm and in mitochondria, and other places) ribosomes translate genetic information in the form of mrna into proteins .

  • Another organelle in the cell is the endoplasmic reticulum (er) while the function of the nucleus is to act as the cell brain, the er functions as a manufacturing and packaging system it works closely with the golgi apparatus , ribososmes , mrna, and trna.
  • Proteins are produced for the plasma membrane, golgi apparatus, secretory vesicles, plant vacuoles, lysosomes, endosomes and the endoplasmic reticulum itself some of the proteins are delivered into the lumen or space inside the er whilst others are processed within the er membrane itself.
