PHOTOSYNTHESIS ATP Production Reactants Products Chemical Equation (formula) Oxygen (absorbed or released) Carbon Dioxide (absorbed or released) Energy required or released? Occurs in which organelle? Main function Presence of electron transport chain (chemiosmosis) and ATP synthase (yes or no) Does it require sunlight? (yes or no) Needs chlorophyll (yes or no) Occurs in which organisms? Brief description of the process Main Steps CELLULAR RESPIRATION What powers ATP synthase? What pumps protons across the membrane? Protons are pumped into the stroma or into the matrix? Final electron acceptor (O2 or NADP+ (NADPH) Where does the high electron potential energy come from? PHOTOSYNTHESIS Light Dependent Reactions Where does it happen? Distinguish between PS I and PS II Light Independent Reactions
