5387660867Enthalpytotal energy2
5387660868Entropytotal disorder3
5387660869ExergonicReleases energy4
5387660870EndergonicEnergy produced5
5387660871ATP structureHas a phosphate group, hydrogen base that consist of two molecules and a one molecule 5-carbon sugar6
5387660872The CycleEndergonic (energy made) ATP Made Hydrolysis of ATP Exergonic (energy loss) ADP + Pi *starts over*7
5387660873OIL RIGOxidation Is Lost (loss of electrons) Reduction Is Gained (gain of electrons)8
5387660874General equation for cell respirationglucose - oxygen - carbon dioxide- water, energy C6H12O6 - 6O2 - 6CO2 + 6H2O9
5387660875phosphorylation reactionphosphate from ATP transfer energy to glucose, requires enzyme (kinase)10
5387660876cell respirationglucose oxidized oxygen reduced requires enzyme (dehydrogenases)11
5387660877Aerobicglycolysis, conversion to Acetyl COA, krebs cycle, ETC: oxidation phosphorylation12
5387660878Anaerobicglycolysis, fermentation13
5387660879glycolysis is in thecytoplasm14
5387660880Acetyl CoA and krebs cycle are in thematrix (low H+, less acidic)15
5387660881Oxidative phosphorylationinner membrane (high H+, more acidic)16
5387660882Glycolysisglucose broken down into 2 pyruvate 2 NADH made and transferred to mitochondria forms 2 net ATP ATP to ADP = phosphorylation 2NAD+ to 2H+ = oxidation/reduction17
5387660883krebs cycleconversion to Acetyl CoA - 2NADH & 2 Acetyl CoA made purpose: complete oxidation of glucose and make energy for ETC18
5387660884ETCelectrons from NADH move to O2 protons pumped into inner membrane space water forms (O2 final electron acceptor)19
5387660885Anemiosmosisprotons diffuse back into matrix trough ATP synthase, makes ATP20
5387660886Fermentationregenerate NAD+, reduce pyruvate end result - alcohol, CO2, lactic acid Alc: bacteria, fungi, plants lactic acid: bacteria, fungi, animals21
5387660887Role in cell reparation of: NAD+ FAD+ O2-NAD+: accept/donate electrons -FAD+: accept/donate electrons - O2: final electron acceptor in ETC22
5387660888substrate level phosphorylationATP made via transfer of phosphate group23
5387660889oxidative phosphorylationATP made from redux reactions24
5387660890chloroplasts-stroma: low H+ -thylakiod: high H+25
5387660891equation for photosynthesis6CO2 + 6H2O + energy --- C6H12O6 + 6O226
5387660892light dependent-utilize water, oxygen released, ATP Made -occurs in thylakoid27
5387660893light independentneed CO2 and ATP to make sugar occur in stroma28
5387660894pigments important for photosynthesischlorophyl a and b, carotenoids29
5387660895ATP madelight absorbed, electrons transferred from photosystem 1 to 2, ETC pumps protons into thylakoid, protons diffuse through ATP synthase and phosphate group bonds to ADP30
5387660896role of ATP and ADP in Calvin cycleATP and ADP: convert carbon into sugar31
5387660897ATP made in mitochondriathrough cell respiration in the matrix32
5387660898ATP made in chloroplastthrough light stroma33
5387660899ATP made in chloroplast and ATP made in mitochondria both:have inter membrane space diffuse of protein have ETC34
