What are the two main parts of a myosin molecule?

Question

Quizplus · Accepted Answer

The myosin molecule consists of a head (also called the motor domain) and a tail, which are the two main parts of the molecule. The head contains the active sites that interact with actin filaments during muscle contraction, while the tail is responsible for binding to other myosin molecules to form thicker filaments. Troponin and tropomyosin are regulatory proteins that are associated with actin filaments, but not myosin. Cross-bridge and head are two terms that are often used interchangeably to refer to the myosin head.
