what are the electron carriers on Complex 1
FMN, Fe/S groups
what are the electron carriers on complex 2?
FAD, Fe/S
What are the Prosthetic groups on Complex 3?
Cyt C, C1, BL, BH, and an Fe/S
what are the electron carriers on Complex 4?
HemeA/HemeA3, CuA, CuB
What are the names oxidized/reduced Coenzyme Q called?
Ubiquinone/Ubiquinol
What are the reduced/oxidized forms of Flavin Proteins?
FMN/FMNH2
What are hte redox forms of Cu
Cu2+/Cu+
What are the redox forms of Fe?
Fe3+/Fe2+
how many ATP per NADH?
2.5
How many ATP per FADH2?
1.5
How many NADH generated by Glycolysis?
2
How do the 2 NADH from oxidation f G3P in glycolysis get to the ETC?
NADH shuttle via Dihydroxyacetone Phosphate and then FAD. Enters Chain at Complex 3. This NADH then yields 1.5, not 2.5 ATP because it's actually via FADH2.
What is the Glycerol Phosphate Shuttle?
The shuttle that takes the NADH generated by G3P oxidation to FADH2 and then to Complex 3.
What are the two enzymes used in the glycerol phosphate shuttle?
Cytosolic Glycerol Phosphate Dehydrogenase

Mitochondrial Glycerol Phosphate Dehydrogenase.
What are the reduced cofactors generated by GLYCOLYSIS
2 NADH, but really 2 FADH2.
What are the reduced cofactors generated by the CAC?
6 NADH
2FADH2
how many molecules of ATP per:
-Acetyl Coenzyme A
-Pyruvate
-Glucose
-10
-12.5
-30
