Difference between actin and myosin

WebDeveloping muscle cells contain thick (myosin) filaments that are 160–170 Å in diameter and thin (actin)filaments that are 60–70 Å in diameter. Young myofibres contain a 7:1 ratio of thin to thick filaments. WebWhen fully lengthened, there is not enough overlap between actin and myosin to generate a lot of contractile force. Conversely, when extremely shortened, myofibrils have …
