Question

_____are made of two intertwined strands of a globular protein called actin.

  1. Microfilaments
  2. Microtubules Intermediate filaments
  3. Intermediate filaments
  4. Cilia

hintHint:

The two intertwine strands of actin form the thinnest cytoskeleton.

The correct answer is: Microfilaments


    • Microfilaments are made of two intertwined strands of a globular protein called actin.
    • The cytoskeleton is the one that provides the basic framework to the cell for its proper functioning. It usually consists of three types of fibers. These are microtubules, intermediate fibers, and microfibers. 
    • Out of these, the microfibers being the thinnest are composed of two strands of globular protein called the actin, that intertwine over each other. 
    • These proteins help the microfibers to give shape and support to cells. It also helps in the movement of organelles. 
    • They have the property of depolarizing easily and changing shape which helps in their overall motility.

    White blood cells use the property of microfilaments to change their shape by depolarising of actin filaments and quickly reaching the site of infection.
