Question
Which of the following fiber is called an actin fiber?
- Microfilaments
- Intermediate filaments
- Microtubules
- All of these
Hint:
The thinnest fiber is composed of actin filaments, in the case of the cytoskeletons.
The correct answer is: Microfilaments
- The microfilaments are fibers that are composed of actin fibers.
- The cells contain various types of the cytoskeleton. Out of these, the shortest and thinnest ones are known as microfilaments. They are composed of actin fibers.
- Microfilaments are usually found in the contraction of muscles. The actin protein present in these has the property of depolarizing easily which allows it to change shape quickly.
- This property is taken as an advantage by the white blood cells, which depolarizes easily, change their shape, and move to the location of the infection quickly.
Microtubules are made up of tubulin protein.
