It uses light to reduce molecules.}Obligate Anaerobes {Ans: Organisms that cannot live where molecular oxygen is present.}Reduction {Ans: any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen)}Citric Acid Cycle {Ans: in cellular respiration, series of chemical reactions that break down glucose and produce ATP; energizes electron carriers that pass the energized electrons on to the electron transport chain}NADH {Ans: the reduced form of NAD+; an electron-carrying molecule that functions in cellular respiration}Light Reactions {Ans: reactions of photosynthesis that use energy from light to produce ATP and NADPH}Redox Reaction {Ans: A chemical reaction involving the transfer of one or more electrons from one reactant to another; also called oxidation-reduction reaction.}Cam Plants {Ans: Store the organic acids made at night in vacuoles and use them for photosynthesis during the day when stomata are closed}Electron Transport Chain {Ans: a series of proteins in which the high-energy electrons from
