- 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
