Notes from NEET topper
Structure of Actin and Myosin:
- Actin and myosin are protein filaments found in muscle cells.
- Actin is a thin filament composed of globular actin (G-actin) subunits, which polymerize to form long, helical actin filaments.
- Myosin is a thick filament consisting of myosin molecules with elongated tail and globular head regions.
