Need it ASAP please answer them all

Caused by a single stimulus, quick cycle of contraction and relaxation is called a __________. The short delay between the stimulus and the onset of the twitch, is called the ________ period. This is the time required for excitation, excitation-contraction coupling, and ________ of the elastic components of the muscle. The force generated during this time is called ________ tension. Once elastic components are taut, the muscle produces external ______. When the external tension moves a load, this is called the _________ phase. The ______ bind to the active sites and form _________ between the thick and thin filaments. Voltage-gated ______ in the ________ open and release ions into the sarcoplasm. A conformational change in the _______ occurs, revealing active sites on the ________. These ions bind to ____ which forms a complex with _______. Voltage sensitive proteins respond to the action potential that spreads down the _________.
