Energy for movement and activity through the action of ATP:
(Similar to a battery that is consumed and recharged):
Answers 
sun
photosynthesis
Energy
ATP
Plants use CO2, water and s____light, which they absorb through the chlorophyll in their leaves. This process,
which is called p______________, releases oxygen and g____________. When these reach the cells, they
activate ATP through a process of combustion, and one phosphate separates from the ATP, creating ADP, P and
e____________. Some of the energy is lost through heat, other is used for movement and activities, and a part
of the energy is used to reunite the phosphate with the ADP, thus once again constructing the A_______
molecule.
