What is the function of the protein 'Titin' in the sarcomere?
Show answer and explanation
Correct answer: It provides elasticity and keeps the thick filaments centered
Titin is a giant elastic protein that extends from the Z-disc to the M-line. It acts like a spring, allowing the sarcomere to recoil after being stretched and keeping the thick filaments aligned in the center.
