Glycolysis Where does it take place? What becomes of the glucose that starts it off? What, eventually, becomes of the 6 carbons from glucose? What regulates the rate of glycolysis? (Know about phosphofructokinase) Krebs Cycle What happens here that allows the ETC to work? What do NADH and FADH 2 do? Are they reduced or oxidized when they leave the Krebs cycle? How do enzymes work? Electron Transport Chain Where does it take place? How does the arrangement of the integral membrane proteins facilitate the ETC? What do the electrons passed in the ETC do?
