Homework Answers
Answer is A) because high energy electrons from NADH AND FADH2 is used for electron transfer and H+ utilization for production of H2O.
Rest options are wrong because-
Protons don't produce ATP while transferring electron it is complex 5 and breakage of ion gradient.
NADh produces 3 electrons not 2.

QUESTION 2 What is the main mechanism of action for oxidative phosphorylation? A Uses the free energy of the proton gradient generated as a result of transferring electrons from NADH OF FADH2 to O2 by a series of electron carriers for ATP production B. Uses the net yield of ATP produced by Glycolysis and the Citric Acid Cycle to produce more ATP. Uses the free energy released during redox reactions in Complexes I-IV (the electron transport chain) and is uncoupled...

Which of the following statements about oxidative phosphorylation is true? a. Oxidative phosphorylation involves the activities of the electron transport chain and the ATP synthesizing machinery. b. The oxidation of NADH is the only way to form ATP. c. ATP is synthesized using the energy that is released when electrons and hydrogen are excreted outside of the cell. d. ATP synthesis occurs during oxidative phosphorylation directly by the reduction of electron carrier proteins in the cytoplasmic membrane.

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...
