Which event directly links the muscle action potential to the start of cross-bridge cycling in skeletal muscle?

easy

AATP binding to myosin

Ca2+ release into the cytosol and binding to troponin

CGlucose entering the muscle cell

DCO2 leaving the muscle cell

EProtein synthesis in ribosomes

Explanation

The action potential triggers Ca2+ release from the SR. Ca2+ binds troponin, allowing myosin to bind actin and start cross-bridge cycling.
