6133229836mesophyllinner tissue of a leaf, contain many chloroplasts1
6133229837stromafluid that fills the inner area of a chloroplast2
6133229838thylakoidsfound in stacks in the chloroplast where the light reactions occur3
6133229839granastacks of thylakoids4
6133229840chlorophyllpigment that absorbs light energy to power the light reactions of photosynthesis5
6133229841stomatapores in the epidermis of a leaf that allow water to leave the plant and carbon dioxide to enter it6
6133229842light reactionsreactions that use carbon dioxide and water to create ATP and NADPH for use in the calvin cycle7
6133229843NADP+an electron acceptor that is reduced and is used to fuel the calvin cycle8
6133229844calvin cyclethe series of reactions where ATP and NADPH are used to form G3P which is then used to form glucose and other organic molecules including amino acids and nucleic acids9
6133229845carbon fixationreactions that use CO2 to make glucose10
6133229846absorption spectrumthe range of wavelengths absorbed by a particular pigment11
6133229847chloroplastthe organelle where photosynthesis takes place12
6133229848products of light reactionsNADPH + ATP + O213
6133229849reactants of calvin cycleNADPH + ATP + CO214
6133229850waterthis molecule splits and allows for an electron to be bumped up to the primary electron acceptor in photosystem II15
6133229851photosystem IIthe location of water splitting16
6133229852p700this is the special chlorophyll that is located in photosystem I17
6133229853p680this is the special chlorophyll that is located in photosystem II18
6133229854chemoautotrophorganisms that produce their own food using inorganic materials - thermophilic bacteria19
6133229855guard cellsresponsible for opening and closing stomata20
6133229856photorespirationprocess where o2 gets substituted for CO2 in the calvin cycle21
6133287031RuBisCoThe enzyme that catalyzes the first step of the Calvin cycle (the addition of CO2 to RuBP). The most abundant protein on Earth!22
6133294401G3PThe molecule that is made from the Calvin Cycle; glucose is formed when two of these molecules combine.23
6133306175Electron Transport ChainA sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP.24
6133310165ATP SynthaseLarge protein that uses energy from H+ ions to bind ADP and a phosphate group together to produce ATP25
6133312952ChemiosmosisProcess by which a Hydrogen pump pumps protons into the thylakoid membrane. H+ passively flows through the ATP synthase which leads to the creation of ATP.26
