(10 pоints) In [а] muscle, which lаcks оbviоus [b], Cа2+ enters the cell through [c] Ca2+ channels and binds to [d] on the SR to increase intracellular Ca2+. These ions then bind to [e], an evolutionary ancestor of troponin C, which activates [f]. This enzyme then phosphorylates one of the two [g] attached to myosin. This phosphorylation changes the position of the [h] so that it can reach the thin filament which is made of polymerized [i]. Contraction in this muscle type ends when an enzyme called a [j] removes the phosphate group that had been added to the answer in Blank #7.
