Which of the following statements about cross-bridges
is false?

1. They are composed of myosin
2. They bind to ATP after they attach to actin
3. They contain an ATPase
4. They split ATP before they attach to actin

The role of calcium in muscle contraction is

1. to break the cross-bridges as a cofactor in the
hydrolysis of ATP

2. to bind with troponin, changing its shape so that
the actin filament is exposed

3. to transmit the action potential across the
neuromuscular junction

4. to spread the action potential through the T
tubules

Myosin filaments are:-

1. thin filament 

2. found only in I band

3. absent from H zone

4. attached to M line
