(1) ATP & how it works
 * **What is ATP (an energy Carrier)?** - Mathilde
 * ATP, or adenosine triphosphate, is an energy molecule often called the “molecular unit of currency” of intracellular energy transfer. It transports chemical energy within cells for metabolism. ATP is always created in the mitochondria, made by photophosphorylation and cellular respiration and is used by enzymes and structural proteins in many processes that take place in the cell. It is a chemical compound in which cells would store or release energy.
 * **What gets continually attached and broken off?** - Mathilde
 * A phosphate group to another molecule releases energy, this is called phosphorylation.
 * **Why?** - Mathilde
 * The phosphate group gets continuously broken off the ATP compound to create energy. As the bond between two of the phosphates are broken, one of the phosphate groups are separated, releasing energy. So when ATP has 3 phosphate groups, it is storing energy for later usage. When it releases one, it turns into ADP, or adenosine diphosphate, which simply has 2 phosphate groups instead of 3, hence the name. ATP is for storing energy, ADP is when it is released. It can then be reattached to form ATP again, for energy storage.
