9524946965Enthalpytotal energy2
9524946966Entropytotal disorder3
9524946967ExergonicReleases energy4
9524946968EndergonicEnergy produced5
9524946969ATP structureHas a phosphate group, hydrogen base that consist of two molecules and a one molecule 5-carbon sugar6
9524946970The CycleEndergonic (energy made) ATP Made Hydrolysis of ATP Exergonic (energy loss) ADP + Pi *starts over*7
9524946972General equation for cell respirationglucose - oxygen - carbon dioxide- water, energy C6H12O6 - 6O2 - 6CO2 + 6H2O8
9524946973phosphorylation reactionphosphate from ATP transfer energy to glucose, requires enzyme (kinase)9
9524946974cell respirationglucose oxidized oxygen reduced requires enzyme (dehydrogenases)10
9524946975Aerobicglycolysis, conversion to Acetyl COA, krebs cycle, ETC: oxidation phosphorylation11
9524946976Anaerobicglycolysis, fermentation12
9524946977glycolysis is in thecytoplasm13
9524946978Acetyl CoA and krebs cycle are in thematrix (low H+, less acidic)14
9524946979Oxidative phosphorylationinner membrane (high H+, more acidic)15
9524946980Glycolysisglucose broken down into 2 pyruvate 2 NADH made and transferred to mitochondria forms 2 net ATP ATP to ADP = phosphorylation 2NAD+ to 2H+ = oxidation/reduction16
9524946981krebs cycleconversion to Acetyl CoA - 2NADH & 2 Acetyl CoA made purpose: complete oxidation of glucose and make energy for ETC17
9524946982ETCelectrons from NADH move to O2 protons pumped into inner membrane space water forms (O2 final electron acceptor)18
9524946983Anemiosmosisprotons diffuse back into matrix trough ATP synthase, makes ATP19
9524946984Fermentationregenerate NAD+, reduce pyruvate end result - alcohol, CO2, lactic acid Alc: bacteria, fungi, plants lactic acid: bacteria, fungi, animals20
9524946985Role in cell reparation of: NAD+ FAD+ O2-NAD+: accept/donate electrons -FAD+: accept/donate electrons - O2: final electron acceptor in ETC21
9524946986substrate level phosphorylationATP made via transfer of phosphate group22
9524946987oxidative phosphorylationATP made from redux reactions23
9524946988chloroplasts-stroma: low H+ -thylakiod: high H+24
9524946989equation for photosynthesis6CO2 + 6H2O + energy --- C6H12O6 + 6O225
9524946990light dependent-utilize water, oxygen released, ATP Made -occurs in thylakoid26
9524946991light independentneed CO2 and ATP to make sugar occur in stroma27
9524946992pigments important for photosynthesischlorophyl a and b, carotenoids28
9524946993ATP madelight absorbed, electrons transferred from photosystem 1 to 2, ETC pumps protons into thylakoid, protons diffuse through ATP synthase and phosphate group bonds to ADP29
9524946994role of ATP and ADP in Calvin cycleATP and ADP: convert carbon into sugar30
9524946995ATP made in mitochondriathrough cell respiration in the matrix31
9524946996ATP made in chloroplastthrough light stroma32
9524946997ATP made in chloroplast and ATP made in mitochondria both:have inter membrane space diffuse of protein have ETC33
