Cellular Respiration PT2 Flashcards
NADH and FADH2 connection to electron transport chain
NADH and FADH2 relay electrons extracted from food to the electron transport chain
Where does most energy come from
10 NADHs, 2 FADH
what is the electron transport chain
Series of molecules embedded inner mitochondrial membrane
what is ETC
breaks energy freefall. from food or oxygen
what is an exergonic reaction
transfer involves oxidation of the original carrier protein and reduction of receiver
Oxygens component
drives downfall of electrons through ETC
what is the energy coupling mechanism
chemiosmosis, drives movement t of H+ from mitochondrial matrix to inter-membrane space
Phosphorylation of ATP process
ATP use exergonic flow of H+
Movement steps of H+
1-H+ ions flow down their gradient through the stator 2.- Each H+ enters a binding site in the rotor, changing the shape of each subunit 3. -Each H+ makes 1 full turn before leaving through a channel into the mitochondrial matrix. 4. -Turning rotor, turns the rod, which is attached to the catalytic knob. 5.-Turn the rod activates catalytic sites in the knob that turn ADP + Piinto ATP!
