The fandango do Ribatejo refers specifically the form of fandango practiced in Ribatejo, Portugal. The dance is usually performed by two Campinos. Figurative meaning
ADP (Adenosine Diphosphate) also contains high energy bonds located between each phosphate group. It has the same structure as ATP, with one less phosphate group. The same three reasons that ATP bonds are high energy apply to ADP's bonds.
ATP is at a high level of chemical potential but the type of energy released from its hydrolysis depends on the application. The short answer is that the hydrolysis of ATP to ADP always releases heat, and if coupled with a cellular process it additionally produces either chemical potential (in another species) or work. Let me back up a bit, and note that ATP is a species that has a high degree of potential energy.
