Question

Put the steps of the interaction between actin and

myosin during muscle contraction in order from
first (1) to last (3).
The myosin head rotates, causing overlap
with actin.
The myosin head attaches to a binding site
on the actin filament.
The myosin head detaches from one
binding site and reattaches to another.​

Answer 1

Answer: If YOU ARE ON THE INSTRUCTION I GIVE THE 1st AND 2nd QUESTION AND ANSWERS

Put the steps of the interaction between actin and myosin during muscle contraction in order from first (1) to last (3).

2 - The myosin head rotates, causing overlap with actin.

1 - The myosin head attaches to a binding site on the actin filament.

3 - The myosin head detaches from one binding site and reattaches to another.

Complete the following statements.

Calcium ions are necessary to activate the binding sites on the actin filaments.

The molecule ATP is required each time the myosin head detaches from one site and reattaches to another.

Answer 2

Answer:During muscle contraction, the sequence of events involving myosin can be summarized as follows:

The myosin head attaches to a binding site on the actin filament.

The myosin head rotates, causing overlap with actin.

The myosin head detaches from one binding site and reattaches to another.

So, the correct order is:

The myosin head attaches to a binding site on the actin filament.

The myosin head rotates, causing overlap with actin.

The myosin head detaches from one binding site and reattaches to another.
