Myosin is known as a motor protein which helps to move the cell, and works with the globular protein, known as actin which polymerize to synthesize actin filaments. They are depends on ATP (a molecule that cells are using to work & live, into mechanical energy). Then this will generates movement, and forces.

Biological macromolecules are synthesized by dehydration

synthesis reactions and are broken down by hydrolysis

reactions.

<h3>What are Biological macromolecules?</h3>

These are formed from smaller compounds and are necessary

for proper life functions of cells. Examples of these

macromolecules include:

  • Carbohydrate
  • Protein
  • Nucleic acid etc.

Dehydration synthesis involves the loss of water molecules in

the process while hydrolysis reaction involves the addition of

water molecules.
