Question

Correctly order the sequence that occurs in muscle contraction

A. Ca release, actin sites exposed, myosin heads bind to actin, ADP and P release from myosin, ATP binds to myosin, ATP split
B. ATP binds to myosin, ATP split, Ca release, actin sites exposed, myosin heads bind to actin , ADP and P release from myosin.
C. Myosin heads bind to actin, Actin sites exposed, ATP split, ATP Binds to myosin, Ca released, ADP and P release from myosin.
D. Ca released, actin sites exposed, ADP and P release from myosin, myosin heads bind actin, ATP binds to myosin, ATP split

Answer 1

The correct order of events in muscle contraction is: Ca release, actin sites exposed, myosin heads bind to actin, ADP and P release from myosin, ATP binds to myosin, ATP split.

Step-by-step explanation:

Correctly order the sequence that occurs in muscle contraction:

1. Ca release
2. Actin sites exposed
3. Myosin heads bind to actin
4. ADP and P release from myosin
5. ATP binds to myosin
6. ATP split

The correct order is: Ca release, actin sites exposed, myosin heads bind to actin, ADP and P release from myosin, ATP binds to myosin, ATP split.
