D)All of the choices are needeD.

Question

Quizplus · Accepted Answer

All three proteins - titin, nebulin, and obscurin - are known to play crucial roles in the formation of new sarcomeres and growth of myofibrils. Titin is responsible for anchoring sarcomeres to the Z-disk and is involved in determining the spacing of sarcomeres during development. Nebulin is a component of the thin filaments and helps regulate their length, while obscurin is involved in linking the myofibrils to the sarcolemma and is important for stability and organization of the sarcomeres. Therefore, all three proteins are needed for proper myofibrillogenesis and growth.
