Question

Chemically cytoskeleton is

  1. Sugar filament
  2. Protein filament
  3. Lipid filament
  4. Vitamin filament

hintHint:

The cytoskeleton gets its strength from its filaments.

The correct answer is: Protein filament


    • Chemically, the cytoskeleton is a protein filament. 
    • The cytoskeleton is a proteinaceous body present in the cytoplasm which ensures that the cell has a proper shape. It gives an accurate framework to the cell. 
    • It is of three types, microfilament, microtubules, and intermediate filament. All of these are composed of different types of protein like tubulin protein, actin filament, etc. based on their functions. 
    • Microtubules are composed of tubulin protein and microfilament is composed of actin filaments. 

    The size of the three types of cytoskeleton varies according to their functions.
