When calcium binds to troponin, the structure of troponin is altered. This results in the removal of tropomyosin from myosin binding sites on actin...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ho...
Answer and Explanation:1 The function played by troponin is binding to the protein called tropomyosin. Therefore, the correct answer is(c) Binds to tropomyosin. Troponin (a...
Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridgecycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regul...

This group includes sarcomeric proteins such as myosin, tropomyosin, troponin and actin, and extracellular matrix proteins such as laminins [59]. Type VI collagen turnover-related peptides were proposed as serological biomarkers for immobilization/remobilization studies, and in partic...
Each sarcomere contains overlapping thick filaments, composed ofmyosinmolecules, and thin filaments, composed of actin,troponin, and tropomyosin molecules. Sliding filament theory of contraction proposes that, during contraction, the myosin binds to the molecules of thin filament to pull the thin filament...
significant portion of tropomyosin. He and his colleagues’ work suggested that “the presence of tropomyosin in actin preparations is not accidental, but… there is an intimate interaction between actin and tropomyosin”. Indeed, they were the first to provide evidence that tropomyosin is an F-...
What is a Tropomyosin? What is an Eccentric Contraction? What is Actin? What are Myofibrils? Discussion Comments Byanon303614— On Nov 15, 2012 I have a question based on the sliding filament theory of muscle contractions. ATP is required to produce the powerstroke, whereby myosin pulls actin...
When calcium binds to troponin, it causes troponin and tropomyosin to change its shape slightly so that they no longer cover the myosin-binding site of actin. The gates have been opened and myosin can finally bind to actin. The second factor—the lack of free ATP—sustains ...
