Endoplasmic reticulum in hindi

Let’s imagine you are a pancreatic cell. Your job is to secrete digestive enzymes, which travel into the small intestine and help break down nutrients from food. In order to carry out this job, you somehow have to get those enzymes shipped from their site of synthesis—inside the cell—to their place of action—outside the cell. The endomembrane system ( endo- = “within”) is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus, which we will cover shortly. Although it's not technically inside the cell, the plasma membrane is also part of the endomembrane system. As we'll see, the plasma membrane interacts with the other endomembrane organelles, and it's the site where secreted proteins (like the pancreatic enzymes in the intro) are exported. Important note: the endomembrane system does not include mitochondria, chloroplasts, or peroxisomes. The rough endoplasmic reticulum ( rough ER) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As these ribosomes make proteins, they feed the newly forming protein chains into the lumen. Some are transferred fully into the ER and float inside, while others are anchored in the membrane. If the modified proteins are not destined to stay in the ER, they will be packaged into vesicles,...

इस आर्टिकल में हम जानेगें की अन्तःप्रद्रव्यी जालिका (Endoplasmic Reticulum)या अंतर द्रव्य जालिका किसे कहते है ? अन्तःप्रद्रव्यी जालिका कितने प्रकार की होती है ? अन्तःप्रद्रव्यी जालिका (Endoplasmic Reticulum) की सरंचना कैसी होती है ?, और अन्तःप्रद्रव्यी जालिका के कार्य क्या होते है ? और अन्तःप्रद्रव्यी जालिका के रूपांतर क्या होते है ? आदि अन्तःप्रद्रव्यी जालिका ( एंडोप्लाज्मिक रेटिकुलम) या अंतर द्रव्य जालिका क्या है ? अन्तःप्रद्रव्यी जालिका झिल्ली युक्त नलिकाओं का एक बहुत बड़ा तन्त्र होता है। यह दोहरी झिल्ली से घिरी होती है। यह जन्तु एवं पादप कोशिकाओं के कोशिकाद्रव्य में अत्यंत सूक्ष्म, शाखित, झिल्लीदार, अनियमित नलिकाओं के घने जाल के रूप में पाई जाती है । यह लाइपोप्रोटीन की बनी होती है और कोशिकाओं में समानान्तर नलिकाओं के रूप में फैली रहती है। कोशिकाओं में इनका विस्तार कभी-कभी केन्द्रक की बाह्य झिल्ली से प्लाज्मा झिल्ली तक होता है। Endoplasm का अर्थ है एंडोप्लाज्मिक रेटिकुलम को झिल्ली युक्त नलिकाओं का पूरा एक नेटवर्क होने के कारण झिल्लियों का तंत्र (system of membrane) भी कहा जाता है। यह परिपक्व RBC को छोड़कर सभी सार्कोप्लाज्मिक रेटिकुलम कहा जाता है। जिसमें Ca की अधिकता होती है। अन्तः प्रद्रव्यी जालिका की संरचना (Structure of Endoplasmic reticulum) एंडोप्लाज्मिक रेटिकुलम की सामान्य संरचना सिस्टर्न नामक झिल्लियों का एक बना एक जाल या नेटवर्क होता है। ये थैली जैसी संरचनाएं साइटोस्केलेटन (cytoskeleton) द्वारा एक साथ रखी जाती हैं। फॉस्फोलिपिड झिल्ली (phospholipid membrane) सिस्टर्नल स्पेस (या लुमेन) को घेर लेती है, जो पेरिन्यूक्लियर स्पेस (perinuclear space) के साथ निरंतर होती ह...

The endoplasmic reticulum (ER) is a large organelle composed of membranous sheets and tubules that start near the nucleus and stretch throughout the cell. The endoplasmic reticulum produces, packages, and secretes many of the products a cell creates. What is Endoplasmic Reticulum? The Endoplasmic reticulum (ER) is one of the important organelles in the cell. Whereas, the nucleus’s function is to serve as the cell brain, the ER acts as a manufacturing and packaging system. The Golgi apparatus, ribosomes, mRNA, and tRNA work closely with ER. Endoplasmic Reticulum Structure is a network of membranes distributed in the cell and connected to the nucleus. The membranes vary slightly from cell to cell, and the size and shape of the ER are dictated by the activity of a cell. For example, prokaryotes or red Before going in to detailed descriptions, first, checkout endoplasmic reticulum diagram: (Image will be uploaded soon) Structure of the Endoplasmic Reticulum (Image will be uploaded soon) The ER membrane system can be anatomically divided into two structures – cisternae and sheets. Cisternae are structurally tubular and form a three polygonal-dimensional network. In mammals, they are about 50 nm in diameter, and in yeast, they are 30 nm in diameter. On the other hand, ER sheets are membrane-enclosed, two-dimensional flattened sacs, which extend throughout the cytoplasm. They are often associated with ribosomes and special proteins called translocons, which are necessary for the ...

• A cell's endoplasmic reticulum (ER) contains a network of tubules and flattened sacs. The ER performs multiple functions in both plant and animal cells. • Endoplasmic reticulum has two major regions: smooth endoplasmic reticulum and rough endoplasmic reticulum. Rough ER contains attached ribosomes while smooth ER does not. • Via the attached ribosomes, rough endoplasmic reticulum synthesizes proteins via the translation process. Rough ER also manufactures membranes. • Smooth endoplasmic reticulum serves as a transitional area for transport vesicles. It also functions in carbohydrate and lipid synthesis. Cholesterol and phospholipids are examples. • Rough and smooth ER are typically connected to one another so that the proteins and membranes made by the rough ER can freely move into the smooth ER for transport to other parts of the cell. The endoplasmic reticulum is a network of tubules and flattened sacs that serve a variety of functions in The two regions of the ER differ in both structure and function. Rough ER has The space inside of the ER is called the lumen. The ER is very extensive extending from the Rough Endoplasmic Reticulum The rough endoplasmic reticulum manufactures membranes and secretory The rough and smooth ER are usually interconnected and the proteins and membranes made by the rough ER move into the smooth ER to be transferred to other locations. Some proteins are sent to the Golgi apparatus by special transport vesicles. After the proteins have been mo...
