  • ATP and ADP Molecule
    • In life , cells use energy in the form of a very high energy molecule, this molecule is known as ATP (  Adenosine Triphosphate) .It is one of the most important compounds living thing uses .  It consists of adenine, ribose ( a five carbon sugar) and three phosphate groups. The phosphate group is very crucial to the store and release of energy.
      • Adenosine Diphosphate is a molecule that is very similiar to ATP  but doesnt have the third phosphate group which is present in the ATP molecule.  When a cell has energy available it stores small amounts by adding phosphate groups.
        • The energy   that the ATP molecule produces is caused by breaking the bonds of the 2nd and the 3rd phosphate groups. It is an efficient way of storing and releasing small amounts of energy for processes.
          • Uses of Biochemical energy of the ATP and ADP molecule- Main uses includes active transport in the form of protien pumps to move ions across concentration gradients and sodium-potassium pumps that pumps sodium ions out of the cell and potassiumn ions into it.  It is also used by the cytoskeleton of the cell for example the cilia and flagelllum for movement of the cell. Other uses of ATP are synthesis of protien and responses to chemical signals on the surface of the cell.
