ATP provides the energy for cells to do what they do; without it nothing would be alive.
ATP consists of adenosine and a 3-phosphate ‘tail’.
ATP is ‘degraded’ (or reduced) to ADP when it releases its energy.
Used ATP molecules are discarded (‘thrown away’) by the cell, never to be used again.
A chemical reaction breaks one of its phosphate bonds.
A phosphate group is added.
Adenine bonds to ribose.
Electrons are excited when ATP is exposed to sunlight.
Transfer chemical energy from food molecules to ATP
Build chemical energy (such as glucose) from sunlight
Help cells exchange gases with their surroundings

It has mass and takes up space.
It always has a pack of matches rolled up in its sleeves.
It has a fairly large nucleus (compared to C and H) and acts as a strong electron ‘grabber’.
We breathe it into our lungs and from there it diffuses into our blood and into our cells.
