Web9) Explain the contraction of muscle cells. A correct answer will include the terms sarcomere, Z line, calcium, sarcoplasmic reticulum, ATP, myofilament, actin, myosin, troponin, neuromuscular junction, tropomyosin, T tubules and binding sites. 10) What is the thick filament of the sarcomere? What is the thin filament? Which is the 'motor protein'? WebMyosin has another binding site for ATP at which enzymatic activity hydrolyzes ATP to ADP, releasing an inorganic phosphate molecule and energy. ATP binding causes myosin to release actin, allowing actin and myosin to detach from each other. After this happens, the newly bound ATP is converted to ADP and inorganic phosphate, P i.
