What is the difference between rough ER and smooth ER?
The main difference between these two terminologies is that the Smooth Endoplasmic Reticulum is known for stocking the lipids and proteins. It is not bounded by ribosomes. Whereas, the Rough Endoplasmic Reticulum is bounded by the ribosomes and also stores proteins.
What are the functions of smooth and rough ER?
The rough ER, studded with millions of membrane bound ribosomes, is involved with the production, folding, quality control and despatch of some proteins. Smooth ER is largely associated with lipid (fat) manufacture and metabolism and steroid production hormone production. It also has a detoxification function.
What is the smooth ER function?
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.
What are two functions of the smooth ER?
The main function of the smooth ER is to make cellular products like hormones and lipids. It also distributes those products throughout the cell and to places in the organism. The smooth ER also regulates and releases calcium ions and processes toxins.
What does the smooth ER do in a plant cell?
Definition of the Smooth ER The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. An organelle is a sub-unit within a cell that has a specialized function. The main function of the smooth ER is to make cellular products like hormones and lipids.
What does the chloroplast do?
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
What is the function of smooth ER?
What is the structure and function of the smooth ER?
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 smooth ER do?
What are the functions of smooth ER?
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.
Does the smooth ER make proteins?
The smooth ER does not have ribosomes on its surface. It makes up proteins and lipids that get exported by the cell. The smooth ER also controls the level in the muscles and detoxifies poisons, alcohol, and. drugs.
What is the shape of smooth ER?
The rough type has a bumpy surface, whereas the smooth ER has a smooth surface. The rough ER is composed of interconnected, sac-like structures, that look like discs arranged in irregular rows. The smooth ER is like a network of interconnected tubules.
What is the definition of smooth ER?
Smooth Endoplasmic Reticulum Definition. The smooth endoplasmic reticulum (smooth ER) is a membranous organelle found in most eukaryotic cells. It is a subset of the endomembrane system of the endoplasmic reticulum.
What is an analogy for smooth ER?
The smooth ER, on the other hand, is an organelle where lipids are synthesized and assigned to become hormones, especially steroid hormones. Thus, it processes steroids, proteins and even carbohydrates. A perfect example of this analogy could be the human brain.
