Cytoskeletons are common for every living organisms present, be it bacteria, archaea, eukaryotes or prokaryotes. It is present in the cytoplasm of a cell and has a very complex network that consists of tubules and filaments that interlink each other1. Cytoskeletons are comprised of three main proteins in eukaryotes and they are usually able to multiply very fast or even disassemble depending on what the cell needs at any given moment.2 The structures of cytoskeletons can differ from one another and is dependant on the type of the cell as well as the organism it is in. 3 Cytoskeletons can perform a wide range of tasks. Primarily, its main purpose is to give a cell its shape and to mechanically resist it from deforming and also assists to make…show more content…
Microfilaments: They are also known as actin filaments and its constituent are G-actin proteins and its polymers. They create a force when the positive end of the filament is pushed against the cell membrane which in this scenario acts as a barrier. They are also seen to track movements of myosin molecules as well and its name is self explanatory as its filaments are primarily made of actin proteins.10 Actin filaments are made when the G- actin (monomer) adds up to form its polymer and hence actin is produced. These produced subunits are later on seen to intertwine with each other and hence produce F-actin chains.…show more content…
