Question

Place the following events in muscle contraction in the correct sequence from first to last. 1. ATP binds to myosin head. 2. Myosin head interacts with actin. 3. ATP is converted to ADP and Pi. 4. Myosin head is cocked back. 5. Myosin head pivots in the power stroke. 6. ADP and Pi are released from myosin.

Answer 1

Answer:

The correct sequence of muscle contraction from first to last is given below

Explanation:

step 1  myosin head interacts with actin

step 2 ATP binds to myosin head

step 3  ATP is converted to ADP and Pi

step 4  ADP and pi are released from myosin

step 5  Myosin head pivots in the power stroke

step 6  Myosin head is cocked back.
