|
What is the overall purpose of oxidative phosphorylation? |
Electron transport resulting in ATP synthesis |
|
|
Where is all the energy derived from? |
Movement of electrons through the electron transport chain which stores energy in a proton gradient |
|
|
How is energy conserved in the process? |
Energy is conserved through the coupling of the endergonic production of ATP to the exergonic process of proteins moving down their electrochemical gradient. |
|
|
What are the electron carriers? |
NAD, Flavoproteins, Iron-Sulfur proteins, cytochromes, and Coenzymes Q |
|
|
Where are each of them found? |
NAD: diffuse away from dehydrogenases in the first two phases of cellular respiration--> complex 1 Flavoproteins: Complex 1 and 2 Iron-Sulfur proteins: 3/4 complexes Cytochromes: B--> complex I and II C--> complex III and intermembrane space A--> complex IV Coenzyme Q: diffuses between complexes |
|
|
Can they accept 1 or 2 electrons? |
NAD:2 Flavoproteins:2 Iron-Sulfur proteins: 1 Cytochromes: C=1, A=1, B=2? Coenzyme Q=2 |
