glycolysis | occurs in cytoplasm one glucose makes 2 pyruvate 2 NADH and 4 ATP |
thioester bond | occurs in enzymes and couples reactions |
Kreb's Cycle Citric Acid Cycle TCA Cycle | mitochondria 2 pyruvate make 2 ATP, and energy, and CO2 as waste light dependent |

phospholipid | hydrophilic head hydrophobic tail |
substrate level phosphorylation | glycolysis and kreb's cycle P removed from intermediate and added to ADP |
CoEnzyme A | krebs cycle, forms thioster bond to help with reactions |
oxidative phosphorylation | does not require oxygen terminal electron acceptor in electron transport chain, then H+ go though ATP synthase |
ETC | electrons enter, couple the acceptor being reduced (exergonic) with pumping protons |
aerobic | oxygen is final electron acceptor |
anaerobic | final electron acceptor is not oxygen (maybe NO3-) |
