Question

What function does the a-band and the i-band perform (pls keep the answer simple)

Answer 1

Answer:

They act as an anchoring point of the actin filaments. Surrounding the Z-line is the region of the I-band (for isotropic). I-band is the zone of thin filaments that is not superimposed by thick filaments (myosin). Following the I-band is the A-band (for anisotropic

Answer 2

Answer:

A-band noticed that one zone of repeated sarcomere. The A-band has a higher content of thick myosin filament, as expected by the area's rigidity. The A-band is the are in the center of sarcomere where thick and thin filaments overlap.

I-Band act as an anchoring point of the actin filaments. Surroundings the Z-line is the region where I-band is the zone of the thin filaments that is not superimposed by thick filaments.
