What is a microtubule?

microtubules are intracellular structures that are shaped as long cylinders or tubes. In general, ONR will have a diameter between 20 and 25 nanometers and may be influenced by the introduction of various drugs. It is used by eukaryotic cells to regulate the shape and control of cell movement in the body.

In the actual structure, the microtubule is mainly composed of tubulin, naturally produced protein. From the external appearance, it appears as a long and stiff unit that is round construction. The walls are usually very durable and somewhat stiff in the composition. Along with playing important roles in the growth and shape of cells, they also help in the process of cell division and motility.

One of the characteristics of the microtubule is that the actual size of the tube will fluctuate depending on the need for function. When the cells need additional material to help cell division or motility, the microtubule will expand the and start the process of producing the necessary material. When the task is complete, it will reduce somewhat and pass to the semi -playing state until it is BUReactivated for further work. The tube may decrease and expand several times during the life of the cell, without apparent reduction in efficiency over time.

Microtubules are considered one of the main components of the cell cytoskeleton, helping in almost all types of cellular functions. It is part of such important tasks such as vesicular transport, cytokinesis and mitosis. Although the work of the microtubule is a lot of understanding, there are still many mysteries about how the tube is activated, such as what causes it to reduce the task and trigger to grow again when it is needed.
