NAME SID 25. Usted below are different steps that occur during the excitation and contraction of a muscle fiber. Please select the correct sequence in which these stages occur. 1) Ca2+ binds to Tropomyosin, causing a conformational change that unblocks cross-bridge binding sites. 2) The Sarcoplasmic Reticulum is depolarized, which opens up Voltage-Gated Channels that release Ca2+ into the cytoplasm. 3) The Action Potential then travels along the cell membrane and down transverse tubules that extend into the muscle fiber....
