Answer:
A electron transport chain and ATP synthase B glycolysis,Lactate fermentation.
Step-by-step explanation:
A Electron transport chain and ATP synthase helps in the generation of oxidized electron carriers because during electron transport chain the reducing equivalents such as NADH and FADH2 donates electron along with proton to become oxidized to form NAD+ and FAD.
B Glycolysis and lactate fermentation occur in absence of oxygen during anaerobic respiration.
