Answer:
Aids energy transfer from a molecule to another
Step-by-step explanation:
ATP aids energy coupling, combining exergonic reactions to endergonic reactions. In PHOTOSYNTHESIS, ATP is produced in the light reactions for Calvin cycle to produce sugar. In CELLULAR RESPIRATION, sugar undergoes oxidized to produce ATP needed to energize cellular metabolism (ATP is the energy currency of the cell).
ATP is a major source of energy for each and every biological process. In PHOTOSYNTHESIS energy is changed to ATP in the light-dependent phase which is used for synthesis in the dark phase.
ATP is a needed in RESPIRATION. ATP is the energy currency of the cells, sometimes called the “molecular currency” of energy distribution.
