What is a smooth ER easy definition?
What is a smooth ER easy definition?
The smooth endoplasmic reticulum, or smooth ER, is an organelle found in both animal cells and plant cells. The smooth ER also regulates and releases calcium ions and processes toxins. It is described as ‘smooth’ to distinguish it from rough ER, which has ribosomes for protein synthesis on its surface.
What is the difference between smooth and rough 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 does rough ER do?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What is the difference between smooth ER rough ER and Golgi apparatus?
SER is mostly found in cells like muscle cells and nerve cells. Rough ER provides proteins and lipids for the Golgi apparatus. Smooth ER provides vesicles for the cis-face of the Golgi apparatus. The rough endoplasmic reticulum is mostly associated with the production, modification, and transfer of proteins.
What is the function of rough ER and smooth 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 function of rough ER?
What are 3 jobs of the 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.
What do smooth ER and rough ER have in common?
Both rough ER and smooth ER have the same types of membranes but they have different shapes. Rough ER is called rough because it has ribosomes attached to its surface. The double membranes of smooth and rough ER form sacs called cisternae. Protein molecules are synthesized and collected in the cisternal space/lumen.
What is the difference between rough and smooth ER?
Ribosomes. Smooth ER: Ribosomes are absent in smooth ER.
What does smooth ER and rough ER have in common?
Rough Endoplasmic Reticulum. In pancreatic cells, the rough ER produces insulin. 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.
What are the similarities between smooth ER and rough ER?
Both formed by tubules and membranous vesicles.
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.
