Actin and myosin work together to help you lift an object in the following way:
- Muscles are tissues of the musculoskeletal system that have the function of generating a force towards the bones with the ultimate goal of performing a movement.
- In order for this function to be carried out correctly, it needs proteins that are found inside the muscle fiber, these proteins are myosin and actin.
- The myosin head in the presence of ATP binds with the actin filaments, in order to generate a minimum slip that later becomes a coordinated and precise movement as lift an object.
- That is, myosin binds to the actin protein to generate the contraction of the muscles, and therefore the movements we make with our extremities.
Therefore, we can conclude that actin is a cellular protein in muscles that is involved in muscle contraction when it connects with myosin.
