ATPase (also called F0F1-ATP Synthase) is a charge-transferring complex that catalyzes ATP to perform ATP synthesis by moving ions through the membrane. The coupling of ATP hydrolysis and transport is a chemical reaction in which a fixed number of solute molecules are transported for each ATP molecule hydrolyzed; for the Na /K exchanger, this is three Na ions out of the cell and two K+ ions inside per ATP molecule hydrolyzed. Web1) the muscle impulse reaches the sarcoplasmic reticulum and calcium is released. 2) thin filaments are pulled over thick filaments. 3) calcium floods the sarcoplasm and binds to troponin molecules leaving active sites. 4) the impulse arrives at the synapse and travels through the transverse tubules. 5) the muscle fiber shortens and contracts. brainerd area used car dealers
