Smooth endoplasmic reticulum (SER) is a type of endoplasmic reticulum consisting of tubular vesicles that lack ribosomes on the outer surface and is involved in the synthesis and storage of lipids. Ribosomes. Rough ER has ribosomes on the outer surface. Smooth ER doesn' thave ribosomes on the outer surface.

What is rough and smooth ER?
Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER looks like sheets or disks of bumpy membranes while smooth ER looks more like tubes. Rough ER is called rough because it has ribosomes attached to its surface. ... Smooth ER (SER) acts as a storage organelle.
What does the smooth ER do?
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 a smooth ER simple definition?
Smooth endoplasmic reticulum (sER) is (a part of) endoplasmic reticulum that is tubular in form and lacks ribosomes. It is present in eukaryotic cells and is associated with lipid synthesis, carbohydrate metabolism, regulation of calcium concentration, and drug detoxification.
What is SER and RER?
Quick look. Rough ER (RER) is involved in some protein production, protein folding, quality control and despatch. It is called 'rough' because it is studded with ribosomes. Smooth E R (SER) is associated with the production and metabolism of fats and steroid hormones.
What is the difference between smooth and rough surface?
As we know that the friction is the force which is opposing in nature, so in a smooth surface there would be no opposing or frictional resistance so , the object can move without any trouble (smoothly) whereas a rough surface is a surface in which there would be a major amount of frictional force present, also it has ...
What is smooth endoplasmic reticulum Class 9?
The smooth endoplasmic reticulum has a tubular form. It participates in the production of phospholipids, the chief lipids in cell membranes and are essential in the process of metabolism. Smooth ER transports the products of the rough ER to other cellular organelles, especially the Golgi apparatus.
Why is the rough ER important?
The function of the rough ER is to provide a place so ribosomes can produce proteins, and proteins are one of the most important things in a cell. Rough ER is the organelle that reads the DNA instructions to make the proteins. Also, the rough ER is involved in the transportation of proteins to the Golgi apparatus.
What is the function of Ser?
sER is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.
How do rough and smooth ER compare structurally and functionally?
Describe the structural and functional distinctions between rough and smooth ER. The primary distinction between rough and smooth ER is the presence of bound ribosomes on the rough ER. ... The smooth ER also functions in detoxification, carbohydrate metabolism, and storage of calcium ions.
What is the relationship between the ribosome and the rough ER?
Rough ER is a host for ribosomes that continually attach to and detach from the ER surface. Essentially, the endoplasmic reticulum and ribosomes work together in order to synthesize proteins and have them transported to their final destination.
What is the structure of a smooth ER?
The Structure of Smooth ER
Smooth ER consists of a long network of a folded, tube-like structure. You can think of it like a pipeline with a lot of twists and turns. The interior of the smooth ER is called the lumen, which is enclosed by a phospholipid membrane, just like the membrane that encloses the entire cell.
What is a smooth surface?
A smooth surface has no roughness, lumps, or holes.
What is a rough surface?
adj. 1 (of a surface) not smooth; uneven or irregular. 2 (of ground) covered with scrub, boulders, etc. 3 denoting or taking place on uncultivated ground.
Which is an example of rough surface?
Rough surfaces are those surfaces which have abrasion and high sliding friction preventing them from sliding fluidly, thereby termed as rough surfaces like sand paper, cement road, new tires and other objects with high sliding friction.
