Describe the energy transfer process relative to both ATP and ADP. ATP has the energy (phosphate group) to donate while ADP can accept energy in the form of a phosphate group. Thus, ATP can be reduced (ATP →ADP + Pi) while ADP can be built into ATP (ADP + Pi →ATP). An organism that derives its energy (generates ATP) from photons of light is called a _________ Phototrophic microorganism. An organism that derives its energy by removing electrons from elemental sulfur would be class...
