Question

A specialized muscle protein, called ______________, makes up the thick muscle filaments. question 8 options: myosin actin myofibril

Answer 1

Hey there! Your answer should be Myosin.

Myosin is a protein whose job it is to help with motion and builds the structure for thick filaments.

Actin works closely with myosin to form the thin filaments sort of as an antagonist for an analogy, and mysofibril works with elogating muscles.

Hope this helps!
