Merdeka.com – Microtubules are cell organelles in the cytoplasm in the form of long, hollow cylinders. Microtubules themselves have an outer diameter of about 25 nm and a long diameter of 12 nm, which are made up of spherical protein molecules called tubulins.
The structure and function of microtubules is regulated by a group of proteins known as Microtubule Associated Proteins (MAPs). Where this protein regulates the length of the microtubules, the arrangement of the microtubules, and the functions of the microtubules. In addition, microtubules will act as belts on conveyers inside the cell, and will help move granules, vesicles, cell organelles, mitochondria and chromosomes through special attachment proteins.
In general, the function of microtubules is to maintain the shape of the cell and play a role in cell movement. In addition, there are several other functions of microtubules that are important to know. The following are the functions of microtubules and their explanations quoted from Microscope Master:
