What is the function of smooth endoplasmic reticulum?
smooth endoplasmic reticulum (SER), meshwork of fine disklike tubular membrane vesicles, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that is involved in the synthesis and storage of lipids, including cholesterol and phospholipids, which are used in the production of new cellular …
What is the function of Golgi apparatus?
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.
Can smooth ER be seen with a light microscope?
Recognize cell organelles, which are visible by regular light microscopy (Nucleus, nucleolus, basophilic rough endoplasmic reticulum, secretory vesicles) and by EM (Golgi complex, lysosomes, rough and smooth ER and others).
What is the main function of the smooth endoplasmic reticulum quizlet?
One of the primary functions of the Smooth Endoplasmic Reticulum is to produce and move lipids, an essential component of a cell’s outer membrane, and steroids.
What happens when the smooth endoplasmic reticulum malfunctions?
A malfunction of the ER stress response caused by aging, genetic mutations, or environmental factors can result in various diseases such as diabetes, inflammation, and neurodegenerative disorders including Alzheimer’s disease, Parkinson’s disease, and bipolar disorder, which are collectively known as ‘conformational …
What is the nucleolus function?
The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.
What is the difference in function between smooth and rough ER quizlet?
What is the difference between rough endoplasmic reticulum and smooth endoplasmic reticulum? Rough endoplasmic reticulum is covered in ribosomes and is involved in the synthesis and production of proteins. Smooth endoplasmic reticulum has no ribosomes and is involved in the production of enzymes and lipids.
What is the main function of the smooth endoplasmic reticulum?
Smooth Endoplasmic Reticulum Definition. Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell. The smooth ER is distinguished from the other parts of the endoplasmic reticulum by the absence of membrane-bound ribosomes.
What are the functions of smooth ER in muscle cells?
The functions of smooth ER include carbohydrate metabolism, regulation of calcium ions, synthesis and metabolism of steroids and lipids, drug detoxification, storage of enzymes, steroids and ions, membrane synthesis, etc. In certain types of muscle cells,…
What is the function of smooth and smooth ER in lipids?
1 Smooth ER is responsible for the synthesis of essential lipids such as phospholipids and cholesterol. 2 Smooth ER is also responsible for the production and secretion of steroid hormones. 3 It is also responsible for the metabolism of carbohydrates. 4 The smooth ER store and release calcium ions.
What are the variants of endoplasmic reticulum?
Endoplasmic Reticulum Diagram. The below diagram shows the variants of endoplasmic reticulum: Rough ER. Smooth ER. Rough endoplasmic reticulum has ribosomes embedded within its structure, giving a “rough” appearance. Smooth endoplasmic reticulum does not have these ribosomes, hence appear “smooth.”. Endoplasmic Reticulum diagram.
