Answer #1

Answer d) Anchors the thick and the thin filaments

Titin is a large, 4.2 MDa, filamentous protein present  in the sarcomere of striated muscle. that is Extended from its N-terminus anchored in the Z-disc to its C-terminus bound to thick filaments in the M-band, titin isresponsible for the passive stiffness of the myocardium exhibited during diastolic filling.

Titin function is to stablize the thick filament, while placing it between the thin filaments.

please give a thumbs up if the answer help you. Thank you!
