7749890567ATP structureadenine(nitrogenous base), ribose(5 carbon sugar), 3 phosphate groups6
7749890568The Cycle of ATPEndergonic (energy made) ATP Made Hydrolysis of ATP Exergonic (energy loss) ADP + Pi *starts over*7
7749890569OIL RIGOxidation Is Lost (loss of electrons) Reduction Is Gained (gain of electrons)8
7749890570General equation for cell respirationC6H12O6 + 6H2O --> 6CO2 + 6H2O + Energy (ATP)9
7749890571phosphorylation reactionphosphate from ATP transfer energy to glucose, requires enzyme (kinase)10
7749890572cell respirationglucose oxidized to release carbon dioxide oxygen reduced to release water requires enzymes11
7749890573Aerobic Respirationglycolysis, then in the presence of OXYGEN conversion to Acetyl COA, krebs cycle, ETC: oxidation phosphorylation12
7749890574Anaerobic Respirationglycolysis then without oxygen available fermentation occurs (only make substrate level phosphorylation 2 ATP total)13
7749890575glycolysis takes place incytoplasm14
7749890576Acetyl CoApyruvate oxidized into __________ ________15
7749890577Oxidative phosphorylationproduces 32-34 ATP, due to chemiosmosis (large production of ATP in Electron Transport Chain)16
7749890578Glycolysisglucose broken down into 2 pyruvate NAD reduced to 2 NADH made and transferred to mitochondria forms 2 net ATP occurs in cytoplasm17
7749890579Krebs cycle- Citric Acid Cyclecomplete oxidation of glucose to release CO2, produces energy for ETC in the form of 6NADH, 2 FADH2, and 2 ATP (after two turns of cycle)18
7749890580Electron Transport Chain (ETC) in cellular respirationelectrons from NADH, FADH2 move to Oxygen to produce water protons pumped into inner membrane space where ATP synthase moves them down their concentration gradient to produce ATP19
7749890581Chemiosmosisenergy couplin mechanism that uses energy stored in the form of an H+ gradient across a membrane to drive ATP synthesis20
7749890582Alcoholic Fermentationregenerate NAD+, reduce pyruvate end result - ethanol & CO2, ex) bacteria, fungi, plants21
7749890583O2- Oxygen gasFinal electron acceptor in ETC of Cell Resp Product when water is spilt in the light reactions22
7749890584substrate level phosphorylationA smaller amount of ATP is formed in glycolysis and the citric acid cycle (Transferring a phosphate directly to ADP from another molecule)23
7749890585oxidative phosphorylationProduction of 32-34 ATP via ETC and chemiosmosis (ATP made from redux reactions)24
7749890586chloroplastsSite of photosythesis25
7749890587equation for photosynthesis6CO2 + 6H2O + solar energy ---> C6H12O6 + 6O226
7749890588Light ReactionsThe energy-capturing reactions in photosynthesis that split water and harness photons of light in electrons that are carried via NADPH and produce energy ATP via electron transport chain embedded in thylakoid membrane27
7749890589Calvin CycleHigh energy electrons from NADPH, H reduce CO2 to produce G3P in a series of steps using the enzyme RUBISCO. (2 turns produce 2 G3P) occurs in stroma28
7749890590pigments important for photosynthesischlorophyl a and b, carotenoids29
7749890591ATP made in Electron Transport Chain in photosynthesislight absorbed, electrons transferred from photosystem 2 to 1, ETC pumps protons into thylakoid, protons diffuse through ATP synthase into stroma where a phosphate is added to ADP to form ATP, NADPH accepts electrons to move the energy to the calvin cycle30
7749890592G3P- glyceraldehyde 3-phosphateis a product of Calvin Cycle can be made into Glucose, Cellulose, Starch or any carbohydrate31

7750427590Activation energyEnergy required to start a reaction33
7750440586CAM plantsopen their stomata at night, incorporating CO2 into organic acids. This allows them to conserve water and not lose as much through transpiration.34
7750459146Lactic Acid Fermentationin the absence of oxygen will oxidze pyruvate in lactic acid and produce NADH (happens in our muscle cells)35
7750480635CO2 Carbon Dioxide-Product of Glucose being oxidized in Citric Acid Cycle -3 of them can be fixed into G3P which can be made into glucose36
7750513828H2O Water-Is split in the light reactions of photosynthesis by photosystem 2 -Is a product of cellular respiration when O2 accepts H from electron carriers NADH and FADH237
