AP BIOLOGY

Detailed explanation-1: -The energy is stored in the links that connect the phosphate groups. A pyrophosphate bond is a type of covalent bond. Meal breakdown and phosphocreatine provide energy for synthesis.

Detailed explanation-2: -ATP stores energy within the bonds between phosphate groups, especially the second and third. This bond is a source of potential chemical energy, and it’s kind of like a compressed spring.

Detailed explanation-3: -This chemical energy is stored in the pyrophosphate bond, which lies between the last two phosphate groups of ATP. When the cells need energy to do any work, ATP cleaves the third phosphate group, releasing a large amount of energy stored in the bond between the third and second phosphate group.

Detailed explanation-4: -Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis).

Detailed explanation-5: -The form of energy that is in ATP is called chemical energy. Chemical energy is a type of potential energy and is stored energy within chemical bonds. ATP, adenosine triphosphate, is a molecule with an adenine nucleotide attached to three phosphate groups. The bonds between the phosphate groups store the energy in ATP.
