What is the definition of Electron Transport Chain?
|
A series of membrane associated electron carriers that pass electrons from reduced coenzymes (NADH and FADH2) to molecular oxygen so as to recover free energy for the synthesis of ATP
|
|
|
Do electron pairs released during glucose oxidation transfer directly to O2?
|
NO, they are transfered to NAD* and FAD
|
|
|
What are the 3 events that occur during e- transport process?
|
-NADH and FADH2 are oxidized to NAD* and FAD
-the e- go through sequential redox of multiple redox centers in 4 enzyme complexed eventually reducing O2 to H2O -protons are kicked out of mitochondria setting up proton gradient that drives oxidative phosphorylation |
|
|
How many mitochondria does an average eukaryotic cell contain?
|
~2000 mitochondria
