10815 Ch 10 Photosynthesis Photosynthesis the process that converts solar energy into chemical energy nourishes almost the entire living world Autotrophs sustain themselves wo eating anything derived from other organism producers Heterotrophs obtain their organic material from other organisms consumers Lightdependent reactions aka light reactions convert light energy into ATP and NADPH oxidation oxidize H20 and release 02 Lightindependent reactions Calvin cycle aka dark reactions reduce C02 to produce sugar reduction use the energy stored in the ATP and NADPH from the lightdependent reactions to do this Photosynthesis converts light energy to the chemical energy of food Choropasts are structurally similar to photosynthetic bacteria 6 02 6 H20 energy C5H1205 6 02 A redox process in which H20 is oxidized amp 02 is reduced Photosynthesis is made up of two parts Light Reactions amp The Calvin Cycle Light Reactions in the thylakoids Split H20 Release 02 Reduce NADP to NADPH Generate ATP from ADP by photophosphorylation Light reactions convert solar energy to the chemical energy of ATP and NADPH Eectrons must be excited to the high energy state energy from sunlight does this High energy electron acceptor has low electronegativity in the Electron Transport Chain The Calvin Cycle in the stroma Forms sugar from C02 using ATP and NADPH Begins with carbon xation incorporating C02 into organic molecules When donating its activated electron the chlorophyll in photosystem II P680 is said to be a very powerful oxidizing agent This is best shown by its ability to Force the oxidation of oxygen in water to oxygen gas One good reason for carrying out the production of oxygen gas 02 in the space surrounded by the thylakoid membranes and not in the stroma of the chloroplasts is that the hydrogen ions released can contribute to the H electrochemical gradient being generated The Calvin cycle uses the chemical energy of the ATP and NADPH to reduce C02 to sugar Calvin Cycle has 3 Phases 1 Carbon Fixation catalyzed by rubisco 2 Reduction 3 Regeneration of the C02 acceptor RuBP Which of the following INCORRECTLY matches a process with its typical location ATP is produced the space between the chloroplast outer and inner membranes Make sure you can look at an illustration and go through the processes taking place throughout the picture
