The difference and relationship between rough endoplasmic reticulum and smooth endoplasmic reticulum

Difference: Rough endoplasmic reticulum.

Most of them are flat cysts, arranged neatly, and a large number of ribosomes are distributed on the surface of the membrane.

It is a secreted protein and lysosome.

A site for protein and membrane protein synthesis, processing, and sorting.

There are no ribosomes on the membrane surface of the slippery endoplasmic reticulum. It's lipids.

An important site for synthesis, a site for the detoxification of certain hydrophobic compounds.

Rough endoplasmic reticulum action:

The function of the rough endoplasmic reticulum is to synthesize protein macromolecules and transport them from the cell or transport them to other parts of the cell. In cells where protein synthesis is vigorous, the rough endoplasmic reticulum is developed. In nerve cells, the development of the rough endoplasmic reticulum is associated with memory.

Smooth endoplasmic reticulum effect:

The function of the smooth endoplasmic reticulum: it is related to the synthesis, detoxification, assimilation of sugars and lipids, and also has the function of transporting proteins.

The endoplasmic reticulum is a fine membrane system within the cell. It is a system of pipes that intertwine membranes distributed in the cytoplasm. Between the two membranes is a flat cavity, sac, or cisterna.

Endoplasmic reticulum is divided into two categories, one is the rough endoplasmic reticulum with ribosomal particles attached to the membrane, and the other is the smooth endoplasmic reticulum with no ribosomes attached to it.

The rough surface is composed of ribosomes and endoplasmic reticulum, which mainly synthesize secreted proteins, membrane proteins and enzyme proteins.

The slippery side does not contain ribosomes. Mainly involved in steroid and lipid metabolism. Because ribosomes play a role in processing and modifying proteins, cancer cells mainly produce immature organelles, which are naturally coarse and slippery.

The rough endoplasmic reticulum can synthesize proteins, and the smooth endoplasmic reticulum can synthesize lipids. The high school biology teacher should have said that. It seems to be from an old textbook.

1. Different appearance: rough endoplasmic reticulum: ribosomal particles are attached to the membrane. Slippery endoplasmic reticulum: smooth on the membrane, no ribosomes attached.

2. Different functions: The function of the rough endoplasmic reticulum is to synthesize proteins and transport them from the cell or transport them to other parts within the cell. Associated with the transport of secreted proteins, preliminary processing of proteins (coiling, folding, glycosylation).

Where protein synthesis is vigorous, the rough endoplasmic reticulum is developed. In nerve cells, the development of the rough endoplasmic reticulum is associated with memory. The function of the slippery endoplasmic reticulum is related to the synthesis, detoxification, and assimilation of sugars and lipids, and it also has the function of transporting proteins.

The function of the rough endoplasmic reticulum is to synthesize protein macromolecules and transport them from the cell or transport them to other parts in the cell.

The rough endoplasmic reticulum is a complex functional structure composed of ribosomes and endoplasmic reticulum composed of a flat membrane sac with a very neat arrangement of liquid masses, and is connected to the outer membrane of the nucleus. Ribosomes attached to the membrane surface; The morphology is mostly plate-like arranged flat sacs; Substances with low or medium electron densities in the mesh cavity; It is mostly distributed in cells with vigorous secretory activity or well-differentiated cells. The function of the rough endoplasmic reticulum is to synthesize protein macromolecules and transport them from the cell or to other parts of the cell.

The endoplasmic reticulum is the base for the synthesis of a series of important biological macromolecules such as proteins, lipids (such as triglycerides) and sugars in addition to nucleic acids. The slippery endoplasmic reticulum also has a detoxification function, such as the slippery endoplasmic reticulum in liver cells contains some enzymes to remove fat-soluble wastes and harmful substances produced by metabolism.
