9. In the electron transport chain picture above, how do electrons move from protein complex I to protein complex II? 1. I need you to remember that "Q" is ubiquinone which gets reduced at proteins l & I, and oxidized at protein III. "Reduced" means gains electrons, "oxidized" means loses electrons. 2. I need you to remember how "Q" moves from protein I to protein Do you remember? Don't overthink it, Preeda. As far as scientists know right now, the...

Oxidative energy generation occurs in three stages: 1. glycolysis 2. TCA cycle 3. electron transport chain. Stage 3 is where most ATP is generated. This process is done by multi-enzyme complexes in the mitochondria (Complex I, Complex II, Complex III, Complex IV and Complex V). If a frame-shift mutation occurred in the gene encoding a protein in one of these complex, identify the one that would cause the most harm and the least harm to the function of the electron...

Cellular respiration: The Electron Transport Chain The breakdown of glucose ends during the Krebs cydle; however, it is important to note that the energy previously contained in glucose is mostly stored in NADH and FADHz. In the last step of celular respiration, the high-energy electrons within NADH and FADH2 are passed within a set of proteins found in the inner membrane of the mitochondrion, collectively known as the electron transport chain. The electrons provide the energy to create ATP, which...
