Answer:

The difference between the microfilaments, intermediate filaments, and microtubules are stated below.

Explanation:

  • Microfilaments:
  1. They are made up of two chains made up of monomeric globular proteins called actin. The chains are coiled around each other.
  2. They have a diameter of about 7 nanometre.
  3. They help in cellular movement.
  • Intermediate Filaments:
  1. They form strands which are made up of fibrous proteins like keratin, vimentin, desmin.
  2. They have a diameter which ranges from 8 nanometre to 10 nanometre.
  3. They have structural function and are required to maintain the cell shape and organelle position.
  • Microtubules:
  1. They are formed when the globular proteins, alpha-tubulin and beta-tubulin form dimer and undergo polymerisation.
  2. They have a diameter of about 25 nanometre.
  3. They form the structural components of flagella, cilia and centrioles. They prevent cell compression.
