Actin is a globular molecule
Actin and myosin are proteins. Protein is a broad category of molecules.
Actin Filaments
Actin is a contractile protein fibers present in muscles.It occurs in two forms a.monomeric G actin b. polymeric F ACTIN.
The ball-shaped protein called actin is the primary component of microfilaments. Actin molecules polymerize to form thin, flexible filaments that are important for cell movement, shape, and division.
Protein.
Actin and Myosin
Microfilaments are made of protein strands called actin.
The rope-like protein that passes through the MBS in G-actin is called F-actin. F-actin is formed by polymerization of G-actin subunits, creating a double helical structure that is essential for the structure and function of the cell's cytoskeleton.
actin
myosin
The regulatory protein associated with actin molecules is called tropomyosin. Tropomyosin binds to actin filaments and regulates the interaction between actin and myosin, thereby playing a crucial role in muscle contraction and other cellular processes. Additionally, tropomyosin helps stabilize the actin filament structure and can influence the binding of other actin-associated proteins.
