What is the underlying mechanism that allows striated muscles to contract more rapidly when very little force is required?   
A)
 
The muscle is shortening so rapidly that some myosin heads are moved to their new position without actually generating any force.   
B)
 
Fewer myosin heads actually attach to the actin, increasing the rate of shortening.   
C)
 
Lighter loads stimulate only a very high speed, low tension isoform of myosin.   
D)
 
Lighter loads stimulate a myosin isoform with a very long unitary displacement.
