In muscle contraction calcium apparently acts to?

Muscle contraction is regulated by calcium ions, which will change thin filament into an activated state by binding to troponin. The binding of calcium to the troponin changes it's shape so the myosin binding sites on the actin (thin filament) are exposedbind to regulatory sites on troponin to remove contraction inhibition

What is the function of actin?

Actin is a globular multi-functional protein that forms microfilaments. Actin takes part in many important cellular processes, including: muscle contraction; cell motility; cell division and cytokinesis; vesicle and organelle movement; cell signaling; and the establishment and maintenance of cell junctions and cell shape.

What function do calcium ions perform during skeletal muscle contractions?

During skeletal muscle contraction calcium ions expose myosin binding sites on to the actin. When a nerve sends a signal to a muscle to do some "action" the release of acetylcholine at the neuromuscular junction triggers calcium to be released into the cytoplasm. At rest, the cell has a low concentration of calcium. When the calcium concentration rises, calcium diffuses over to the muscle protein fibers and causes a conformational change. Calcium binds to the troponin and causes it to rotate slightly which forms a crossbridge that drags along the actin fiber and shortens it thus creating muscle fiber contraction.

What is the structural role of protein?

Structural proteins are fibrous proteins. The most familiar of the fibrous proteins are the keratins. This forms skin, fur, hair, nails, hooves, horns, beaks and feathers. Other structural proteins are the actin and myosin proteins of muscle tissue, tendons and ligaments.Structural proteins are proteins that build up our tissues or body. actin, myosin, clotting factors are some of the structural proteins. They give up a shape and rigidity to our cells or tissues and ultimately to our body (muscle).

What Steps in muscle contraction require calcium ions?

Calcium ions bind to troponin, changing troponin's shape
