<span>Cross bridges are created when myosin heads bind to ATP. This phenomenon is basically muscle contraction at work. In order for myosin heads to be bound with ATP at the actin active site, it must be excited with Calcium.
Once myosin heads bind with ATP, it begins to slide and perform muscle contractions in the body, allowing a person to move.</span>
Binary fission occurs in single-celled organisms only and mitosis is just one cell dividing into two (eukaroytic cells)
Answer:
Both Bacteria and Archaea are prokaryotes, single-celled microorganisms with no nuclei, and Eukarya includes us and all other animals, plants, fungi, and single-celled protists – all organisms whose cells have nuclei to enclose their DNA apart from the rest of the cell.

Answer:
<h2>5.storage of energy</h2>
Explanation:
- Proteins are important biomolecules that are a type of macromolecule.
- This macromolecule is made up of a monomer that is called amino acid.
- There are many functions of the protein molecules in living organisms.
- They play an important role as bodybuilding molecules, as enzymes, as transporter molecules, and many more.
- Most of the enzymes are made up of the protein molecules and regulate the metabolic process of the living organisms.
- Certain proteins are present in the plasma membrane of the cells and play an important role in the transport of the substances across the cells, recognition of certain foreign particles, and some other functions.
- They also play an important role in the immune system.
- The main storage molecules of energy are carbohydrates and fats so storage of energy is not considered as the major function of the proteins because they do not involve as carbohydrates and fats.
