Answer:
The correct answer will be- ATP binds to the myosin head
Explanation:
The muscle contraction is associated with the ATP binding to the myosin head which triggers the formation of the cross-bridge between the myosin head to the actin on muscle and pulling the sarcomere.
The cross-bridge cycle pulls the sarcomere thin filaments which require energy provided by the ATP as ATP when binds the mysoin head allows the detachment of the myosin to the actin.
Thus, ATP binds to the myosin head is the correct answer.

Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. parent. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. Meiosis is the type of cell division that produces gametes.
Can you give me the options?? ill be able to help you with more info!!
