Step 11 of skeletal muscle contraction:__________.
malfutka [58]

Answer:

The suitable option will be - B

B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.

Explanation:

Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.  

Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.  

So, we can say that option B is correct.
