Myosin and actin are -

The correct answer is Muscle protein.

In News

• Myosin and actin are fundamental components of muscle contraction mechanisms.

Key Points

• Myosin and actin are the primary proteins involved in muscle contraction.
• They work together to convert chemical energy into mechanical energy.
• Myosin is a motor protein that interacts with actin filaments to produce movement.
• Actin filaments slide past myosin filaments, causing muscle fibers to contract.

Additional Information

• Myosin
  • Myosin is a type of motor protein that uses ATP to drive the movement of actin filaments.
  • It plays a crucial role in muscle contraction and other cellular movements.
• Actin
  • Actin is a globular protein that forms long chains or filaments.
  • These filaments are critical for various types of cell motility and structure.
• Muscle Contraction Mechanism
  • Muscle contraction occurs through the sliding filament model, where actin and myosin filaments slide past each other.
  • ATP binds to myosin, allowing it to detach from actin and reattach further along the filament, creating a power stroke.
• ATP (Adenosine Triphosphate)
  • ATP is the energy currency of the cell and is necessary for muscle contraction.
  • It provides the energy required for myosin to move along actin filaments.
