Biology Question on Skeletal System

The amoeboid movement results from

A

interactions among actin, myosin and ATP, etc

B

coordinated beats of cilia

C

whip-like action of flagella

D

action by the mitotic spindle, similar so, what happens during mitosis and meiosis

Answer

interactions among actin, myosin and ATP, etc

Explanation

Solution

Amoeboid movement is the most common mode of locomotion in eukaryotic cells. Molecular mechanism involves participation of microdomain signalling. As, microdomains trigger and maintain active polymerisation of actin filaments, their propagation leads to interaction with myosin that generates retrograde flow. ATP is utilised in this process.
