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

Authors Terrence Sanvictores 1 ; Donald D. Davis 2. The endoplasmic reticulum ER is a structure found within the cytoplasm of eukaryotic cells. The RER is termed "rough" due ribosomal attachments to the surface compared to the SER, which does not have ribosomes.

Flat, bag-like compartments within the ER network; crucial for various cell functions such as protein synthesis, fat breakdown, and calcium storage. After the mRNA sequence has been translated into a polypeptide chain , where does it go? Help us improve. Trending in News. Change Language. Thus, eliminate all the other choices that do not have label 1 correctly associated with proteins in any way or form. Before we get into rationalizing the answer, let us be oriented with what the diagram is labeled with:. Thus it makes sense that the label 1 is a ribosome. Diagram of the Endoplasmic Reticulum. Engineering Exam Experiences. 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. Save Article. Table of Content What is Endoplasmic Reticulum? Like Article. The endoplasmic reticulum ER is a network of membrane-enclosed tubules and sacs cisternae that extends from the nuclear membrane throughout the cytoplasm.

Among many cell organelles present in the cell, the endoplasmic reticulum ER is the largest membrane-bound organelle of the eukaryotes, but the prokaryotes lack these organelles. Although the endoplasmic reticulum is present in most eukaryotic cells, some cells like red blood cells and embryonic and egg cells lack it.

Thus it makes sense that the label 1 is a ribosome. Contribute to the GeeksforGeeks community and help create better learning resources for all. Similar Reads.
