Exercise 2

Analyzing the action of a muscle contraction inhibitor
An ATP analog, , -methylene-ATP, in which a -CH₂ - group replaces the oxygen atom between the - and - phosphorus atoms, is a potent inhibitor of muscle contraction. At which step in the contraction cycle would you expect , -methylene-ATP to block contraction
