3.3.4 Explain how adenosine can gain and lose a phosphate molecule.
Adenosine Triphosphate is an energy rich chemical compound which serves as the immediate source of energy of most of the reactions in the body, especially muscle contraction.
ATP is made up of a smaller compound (adenosine) and three phosphate groups (hence the name triphosphate).

3.3.4 Explain how adenosine can gain and lose a phosphate molecule.
Some molecules release a great deal of energy when their bonds are broken. ATP is one such high energy molecule. It is a kind of “currency” which powers all sorts of biological work.
When it is broken down, ATP releases energy. ATP is broken down into Adenosine Diphosphate. That is, adenosine plus two phosphates and a separate phosphate group.
