-a molecule present in all living cells and acting as a energy source for metabolic processes
-a substance involved in energy metabolism formed by the breakdown of adenosine triphosphate
-an enzyme that catalyzes the synthesis of ATP from ADP and phosphate
-a class of light-absorbing pigments used in photosynthesis
-a stack of thylakoids in a chloroplast
-the initial reactions in photosynthesis, including the absorption of light by photosynthesis I and II, the passage of electrons along the electron transport chains, the production of NADPH and O2 , and the synthesis of ATP through chemiosmosis
-the conversation of light energy into chemical energy stored in organic compounds
