5968950784GlycolysisThe First Step of Cellular Respiration; occurs in cytoplasm0
59689507851 Glucose is broken into two pyruvate, releasing 2 ATP. This is when and where NAD+ steals its' e-, turning it into NADH.Events of glycolysis:1
59689507862 pyruvate are converted into 2 Acetyl CoA. The 2 Acetyl Coa then diffuse into the Mitochondria. They are then used in the Kreb's Cycle.Events of pyruvate oxidation2
5968950787Kreb's CycleThe second step of Cellular Respiration; occurs in the mitochondrial matrix3
5968950789Electron Transport ChainThe Third Step of Cellular Respiration; occurs in the inner membrane of mitochondria4
5968950790FADH2 and NADH transfer their electrons to the ETC. The electrons pass down a series of proteins, pumping out H+ atoms every time they go down a level. The Electron finally stops when it reaches Oxygen (the last electron receptor) and water is produced.Events of the electron transport chain5
5968950791H+ atoms then diffuse from High to Low concentration; from the intermembrane space, through ATP synthase, into the matrix. This generates energy to form ATPAfter the ETC is completed6
5968950792cellular respiration reaction (equation)C6H12O6 (Sugar) + 6O2 ( Oxygen) --> 6CO2 ( Carbon Dioxide) + 6H2O (Water)+ ATP7
5968950793aerobic cellular respirationreaction that uses glucose and oxygen to create ATP molecules. Carbon dioxide and water are by products.8
5968950794anaerobic cellular respirationreaction that uses glucose as a reactant to create a few ATP molecules. No oxygen is used in this reaction.9
5968950795glycolysisstep of cellular respiration where 1 glucose is broken down into 2 pyruvate10
5968950796reactants of glycolysis1 glucose, 2NAD+, 2 ATP11
5968950797products of glycolysis2 pyruvate, 2NADH, & 2ATP12
5968950798reactants of krebs cycle2 acetyl CoA, 2ADP + P, 6NAD+ & 2FAD13
5968950799products of krebs cycle4CO2, 2ATP, and 6NADH &2 FADH214

5968950806oxidative phosphorylationOcurrs in ETC & chemiosmosis20
5968950808inner membrane of mitochondrialocation of ETC21
5968950809oxygenlast acceptor of ETC22
5968950810chemiosmosisproton motive force through an ATP synthase, as a result of H+ gradient (movement of hydrogens pumped out from ETC through a protein, then through ATP Synthase, moving from High Conc. to Low Conc)23
5968950811ATP synthaseenzyme that helps in the production of ATP24
5968950812alcohol fermentationanaerobic respiration that produces carbon dioxide and ethanol and recycles NAD25
5968950813How does Alchohol Fermentation occur?During Glycolisis, 2 NAD+ takes an electron to become NADH. 2 NADH then donates an electron to 2-Acetaldehyde, producing Ethanol. The loop between 2 NAD + and 2 NADH occurs forever.26
5968950814lactic acid fermentationanaerobic respiration that produces lactate and recycles NAD27
596895081536 or 38number of ATP made in aerobic cellular respiration28
5968950816cellular respirationreaction that uses glucose and oxygen to create ATP molecules. Carbon dioxide and water are products29
5968950818The site of Oxidative Phosphorylation isthe Electron Transport Chain; inner membrane of mitochondria30
5968950819During Oxidative Phosphorylation,electrons are transfered from electron donors to electron acceptors such as Oxygen31
5968950821Glycolysis and The Kreb Cycle make ____ ATP each2 (Total of 4, 2 from Glyc, 2 from KC)32
5968950822What makes ADP + P turn into ATP during Glyco and the Kreb Cycle1. Substrate Level Phosphorylation 2. 4 ATP are produced in total33
5968950823Lactid Acid and Alcohol Fermentation are both forms ofAnaerobic Cellular Respiration34
5968950827During Cellular Respiration, ________ is reduced and _____ is oxidizedOxygen (to H2O); Glucose (to CO2)35
5968950828The order of Electron Transport in MitochondriaNADH -> ETC -> H+ Gradient -> Chemiosmosis36
5968950829Lactate is formed in Lactid Acid Fermentation toregenerate NAD+37
5968950830The whole process of cellular respiration produces 36 or 38 ATP from one glucose. The rest of the energy is conerted intoheat energy38
5968950831Gaining an electron isreduction39
5968950832Losing an electron isoxidation40
