Learn how proteins, specifically myosin and actin, use ATP to produce movement in muscles. Understand the role of ATP hydrolysis in this process. This is a key part of how muscles function, converting chemical energy into mechanical energy.
7 paź 2024 · The interaction between myosin and actin is initiated when the myosin head binds to an actin filament. This binding triggers the hydrolysis of ATP, which releases energy and causes a conformational change in the myosin head. This change propels the myosin along the actin filament, resulting in muscle shortening.

Each sarcomere consists of thick filaments of myosin, shown in purple, and thin filaments of actin, shown in orange. A sarcomere contracts when its actin filaments slide past its myosin filaments. Contraction shortens the sarcomere but does not change the length of the actin or myosin filaments.
