Cytosome

A cytosome is a cell structure that is located outside its nucleus. It plays an important role in metabolism and transport of substances between cellular compartments.

The cytosome is part of the cytoplasm of the cell and consists of many membrane vesicles called vesicles. These vesicles contain various molecules such as proteins, lipids and carbohydrates that are essential for cell functioning.

The functions of the cytosome include transporting molecules from one part of the cell to another, recycling metabolic waste, and synthesizing new molecules. For example, the cytosome can transfer proteins produced in the endoplasmic reticulum to the Golgi apparatus for further processing and transport.

In addition, the cytosome plays an important role in autophagy, a process in which the cell utilizes its own structures and molecules to obtain energy and building blocks. In this process, the cytosome forms a double membrane that surrounds the structures being utilized and forms an autophagy vesicle.

Thus, the cytosome is an important cell structure, playing a key role in the metabolism and transport of molecules within the cell. Its functions include the transport of molecules, the disposal of metabolic waste, and participation in the process of autophagy.



A cytosome is a cell structure that is located outside the nucleus and performs a number of important functions in the cell. It is a small structure that consists of several proteins and nucleic acids. Cytosomes are part of the cell's cytoskeleton and play an important role in its functioning.

The cytosome consists of two main components: the cytoskeleton and the cytoplasm. The cytoskeleton is a network of protein filaments that form the framework of the cell and provide its mechanical stability. Cytoplasm is the internal environment of the cell in which all biochemical processes occur.

Functions of the cytosome:

  1. Regulation of cell shape and size. The cytosome is involved in regulating the shape and size of the cell, ensuring its stability and proper functioning.
  2. Transportation of substances. The cytosome plays an important role in transporting substances within the cell. It transports proteins, fats, carbohydrates and other nutrients from one end of the cell to the other.
  3. Participation in cell division. The cytosome is also involved in cell division by ensuring proper separation of the cytoplasm and nucleus between daughter cells.
  4. Participation in the cell cycle. The cytosome is associated with the cell cycle, the process that determines when a cell should divide and grow.

Thus, the cytosome is an important cell structure that is involved in many processes related to its functioning. It plays a key role in maintaining cell shape and size, as well as in nutrient transport and cell division.



Cytosome is a membrane organelle of a cell, but what is it? It is an ultrastructural, morphologically and functionally similar structure and is found on the cytoplasmic membrane of all eukaryotic cells. Without the cytosome, the function and metabolism of the cell could be irreparably impaired. Cytosomes participate in the regulation of the flow of substances into the cell flowing through them and, conversely, in regulatory processes and maintaining the membrane potential of the cell. An example is intracellular lysosomes, which contain enzymes for digesting nutrients delivered from the cytoplasm during digestion. Detoxification and, due to this, the cessation of excessive exposure to toxins on the cell is also largely carried out through the cytosome. A large number of cytosomes of different sizes are found in the plasma of animal cells, plant cells, and fungal cells. Consequently, the cytosome plays a diverse role in the cell and is an integrator, the functional center of the cell.



The cytosome is a large organelle, clearly visible in a light microscope, containing two “worlds”: a structure similar in structure to the nucleus and rings of prokaryotes, including the corresponding enzyme systems and many messenger RNAs, and a much more “cosmic” world, including vacuoles, twisting tubes and much more, the totality of which is sometimes called mitochondria and plastids at the same time. Without correct isolation of the cytosome, it is impossible to imagine the structure of the eukaryotic cell as a whole.
