PROCESS OF SLIDING FILAMENT THEORY

muscle contraction stops

Ca2+ removed which shifts actin filaments to original position, blocking binding sites

muscle contracts

Ca2+ binds to troponin, shifting the actin filaments, which exposes binding files

Ca2+ released

action potential generated, which stimulates muscle
