6895242430Enthalpytotal energy2
6895242431Entropytotal disorder3
6895242432ExergonicReleases energy4
6895242433EndergonicEnergy produced5
6895242434ATP structureHas a phosphate group, hydrogen base that consist of two molecules and a one molecule 5-carbon sugar6
6895242435The CycleEndergonic (energy made) ATP Made Hydrolysis of ATP Exergonic (energy loss) ADP + Pi *starts over*7
6895242436OIL RIGOxidation Is Lost (loss of electrons) Reduction Is Gained (gain of electrons)8
6895242437General equation for cell respirationglucose - oxygen - carbon dioxide- water, energy C6H12O6 - 6O2 - 6CO2 + 6H2O9
6895242438phosphorylation reactionphosphate from ATP transfer energy to glucose, requires enzyme (kinase)10
6895242439cell respirationglucose oxidized oxygen reduced requires enzyme (dehydrogenases)11
6895242440Aerobicglycolysis, conversion to Acetyl COA, krebs cycle, ETC: oxidation phosphorylation12
6895242441Anaerobicglycolysis, fermentation13
6895242442glycolysis is in thecytoplasm14
6895242443Acetyl CoA and krebs cycle are in thematrix (low H+, less acidic)15
6895242444Oxidative phosphorylationinner membrane (high H+, more acidic)16
6895242445Glycolysisglucose 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
6895242446krebs cycleconversion to Acetyl CoA - 2NADH & 2 Acetyl CoA made purpose: complete oxidation of glucose and make energy for ETC18
6895242447ETCelectrons from NADH move to O2 protons pumped into inner membrane space water forms (O2 final electron acceptor)19
6895242448Anemiosmosisprotons diffuse back into matrix trough ATP synthase, makes ATP20
6895242449Fermentationregenerate NAD+, reduce pyruvate end result - alcohol, CO2, lactic acid Alc: bacteria, fungi, plants lactic acid: bacteria, fungi, animals21
6895242450Role in cell reparation of: NAD+ FAD+ O2-NAD+: accept/donate electrons -FAD+: accept/donate electrons - O2: final electron acceptor in ETC22
6895242451substrate level phosphorylationATP made via transfer of phosphate group23
6895242452oxidative phosphorylationATP made from redux reactions24
6895242453chloroplasts-stroma: low H+ -thylakiod: high H+25
6895242454equation for photosynthesis6CO2 + 6H2O + energy --- C6H12O6 + 6O226
6895242455light dependent-utilize water, oxygen released, ATP Made -occurs in thylakoid27
6895242456light independentneed CO2 and ATP to make sugar occur in stroma28
6895242457pigments important for photosynthesischlorophyl a and b, carotenoids29
6895242458ATP 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
6895242459role of ATP and ADP in Calvin cycleATP and ADP: convert carbon into sugar31
6895242460ATP made in mitochondriathrough cell respiration in the matrix32
6895242461ATP made in chloroplastthrough light stroma33
6895242462ATP made in chloroplast and ATP made in mitochondria both:have inter membrane space diffuse of protein have ETC34
