What are the two parts of the endoplasmic reticulum?
The ER can be classified in two functionally distinct forms: smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER).
What are the parts of the endoplasmic reticulum?
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.
What is the second function of ER?
The endoplasmic reticulum (ER) is the largest membrane-bound organelle in eukaryotic cells and performs a variety of essential cellular functions, including protein synthesis and processing, lipid synthesis, and calcium (Ca2+) storage and release.
What two types of substances do ER packaged?
It modifies and packages proteins and lipids made within the cell, and sends them out to where they are needed. The cell's endoplasmic reticulum (ER) generates biological raw materials, packaging them in membrane-enclosed bubbles called vesicles, for transport to the Golgi.
What is endoplasmic reticulum class 9th?
The large network of membranous sheets and tubes is called endoplasmic reticulum. They are filled with fluids and carries materials throughout the cell due to which it is also called transport system of the cell. It transports materials between the regions of cytoplasm or between the cytoplasm and nucleus.
Where is the ER located in a cell?
The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1). The entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.
What is smooth ER do?
The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. ... The smooth endoplasmic reticulum also carries out the metabolism of carbohydrates and steroids.
Which of the following is part of the Endomembrane system?
The endomembrane system includes: the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and the plasma membrane.
What proteins are made in the rough ER?
Proteins synthesized by the rough ER include the prominent milk protein casein, and whey proteins. These proteins are packaged into secretory vesicles or large micelles and travel through the Golgi network before fusing with the plasma membrane, releasing their contents into milk ducts.
Which of the following is not a function of ER?
Which one of the following is not a function of Rough endoplasmic reticulum? Answer: Membrane biogenesis.
What is the mitochondria function?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What is the Golgi apparatus structure?
The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.
What does Golgi apparatus do?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
