Physiology

When energy is derived from creatine phosphate to cause muscle contraction, what is the first step in this transfer of energy -

The creatine phosphate transfers its energy to the cross bridges to cause them to become locked

The creatine phosphate causes the power stroke of the cross bridges

The creatine phosphate transfers its energy to the actin filament

The energy of the creatine phosphate is used to convert ADP to ATP
