AP Bio Chapter 9 Part 2 Flashcards
Ph of intermembrane space
High acidity (lots of H+)
Why is membrane folded the way it is in regards to CC
To fit more of the pumps that hold the molecules
Where do protons go in oxidative phosphorylation
Pumped across membrane to intermembrane space
Where do electrons go in oxidative phosphorylation
Pump to pump through membrane gradient
How is water formed in oxidative phosphorylation
Electrons are transferred to cytochrome c complex, then meet w oxygen and water is formed
Where do the electrons come from in oxidative phosphorylation
NADH or FADH2 and end up on oxygen
Chemiosmosis
A way how ATP is produced
How ETC establishes a proton gradient (electrochemical)
How can protons diffuse back to matrix in oxidative phosphorylation
Through a proton channel
What’s the only channel available in the inner membrane
ATP synthesis
What happens as protons diffuse through ATP synthase in oxidative phosphorylation
The free energy that is released is used to catalyze ATP formation from ADP and a phosphate group
What’s basically chemoheterotrohic energy processing
Basic all the metabolic pathways that occur when you eat something
Inputs oxidative phosphorylation
10 NADH
2 FADH2
O2
Outputs of oxidative phosphorylation
~32-40 ATP
H2O
10 NAD+
2 FAD
Roughly is oxygen is present and electrons go to ETC, then how many ATP per NADH
3
Roughly is oxygen is present and electrons go to ETC, then how many ATP per FADH2
2
What process is more efficient regarding oxygen
Anaerobic < aerobic
Aerobic is 19x more efficient
