Ch 7 cellular respiration The purpose of cellular respiration is to make ATP o Process of burning sugar with fuel for the process o All cells carry out respiration C 6 12+66O -> 2CO + 6H 2 + ene2gy Oxidation- reduction reactions (redox reactions) o Oxidation gains oxygen, loses hydrogen Exergonic reaction o Reduction gains hydrogen, loses oxygen Endergonic NADH> high energy electron carrier Overview o Glycolysis turns glucose>>> pyruvate +NADH+ 2 ATP Does not require oxygen/ or any gases o In between step turns pyruvate into acetyl coa forming CO2 o Citric acid cycle > NADH+ 2 ATP Carbons bond to make citric acid and then are broken off to make more CO2 Will stop if there is no oxygen o Oxidative phosphorylation (32 ATP) Electron transport chain makes water with H+ gradient Called chemiosmosis H+ come from NADH made throughout the process ATP made using ATP synthase pump Uses H+ gradient as energy Fermentation o Anaerobic means “without oxygen” o Anaerobic respiration uses a substance other than O2 as the final electron acceptor o Fermentation> “an electron dump” Citric acid cycle stops in the absence of oxygen because NADH quits giving H+ to make water and NAD is needed for the citric acid cycle Glycolysis always keeps going and fermentation helps regenerate NAD 2 Electrons are dumped onto pyruvate to form lactate This process is reversible Animals and some bacteria can fermentate Ethanol is fermentation performed by plants such as yeast Carbonation in ethanol is CO2 In plants:pyruvate turns into acetaldehyde and then turns to ethanol o ATP works as a feedback inhibitor to “turn off” the enzyme that performs glycolysis
