Transcribed Image Text:If you could generate a sarcomere with a catalytically dead myosin Il that could bind ATP, but not hydrolyze it, what would you
expect?
A the actin filaments would lengthen because there would be excess ATP in solution
B the mutant myosins from the sarcomere would bind to actin but not undergo the power stroke to contract
the sarcomere would contract as usual
the sarcomere would be stuck in a contracted state, unable to relax
the mutant myosins from the sarcomere would bind to ATP and not bind to the actin
