Quiz: Test Your Knowledge About Cytoskeletal Or Cytoskeleton Structures Of A Cell

Let’s start the quiz

Cytoskeletal structures are visible under the electron microscope. These structures are of three types, the first one is Microtubles, second Microfilaments and the last one is Intermediated filaments. Microtubules are hollow cylinders with their walls consists of the contractile protein tubulin. these subunits are arranged alternative in helix and their lateral projections from cross bridges. Calcium, magnesium, GTP, and calmodulin are required to assemble the microtubule subunits. Microfilaments are the soli rods made up of Globular protein and filamentous protein. Intermediate filaments are solid, noncontractile filaments made up of eight protofilaments. They are larger than microfilaments and are present in all the eukaryotic cells except RBC's. So, take this quiz and increase your knowledge about cytoskeletal structures.
