1. Myosin and actin are arranged as rod-like structures, parallel to each other and also to the transverse axis of the myofibrils. 2. Actin filaments are thinner as compared to the myosin filaments, hence are commonly called thin and thick filaments respectively. Regarding 1 and 2 :

Step 1
Myosin and actin are arranged as rod-like structures, parallel to each other and also to the transverse axis of the myofibrils. This statement is true. Myosin and actin are the two main proteins that make up the muscle fibers. They are arranged in a specific Show more…

Myosin, a motor protein, is shown in the image. Label the structure of myosin and then determine which statements about myosin are true? Answer Bank: During muscle contraction, thick and thin filaments slide past each other causing an overall lengthening of the muscle. The tail of the myosin molecule acts as a molecular lever and binds ATP. The myosin-actin reaction cycle is powered by ATP hydrolysis. The interaction between myosin and actin converts chemical energy to mechanical work.
