Thick Myofilaments
Thick Myofilaments include Myosin protein
Myosin- Myosin is the primary component of thick filaments in muscle cells. It is a motor protein that works in coordination with actin. It is responsible for converting chemical energy, in the form of ATP (adenosine triphosphate), into mechanical work. Myosin molecules have a globular head and a long tail. The heads bind to actin, forming cross-bridges, and undergo conformational changes that cause muscle contraction.
Contractile Proteins, Types and their Functions
Contractile proteins are a group of proteins responsible for the contraction and movement of muscles in living organisms. These proteins work together in a highly coordinated manner to enable muscle cells to shorten and generate force, allowing for various types of movements. In a muscle cell, there are two types of myofilaments-Thin Myofilaments and Thick Myofilaments.
