Homework Answers
22. What is the name of the energy product of the TCA cycle?
- 1 GTP
- 3 NADH/1 FADH2 (electrons carriers for oxidative phosphorylation
to produce ATP)
-2 CO2
23. At which complex in the ETC do NADH products arrive?
complex I (NADH dehydrogenase)
24. At which complex in the ETC do the FADH products arrive?
complex II (FADH2 dehydrogenase)
25. What is the fate of H+ in the ETC?
Hydrogens from NADH deliver enough energy to make 3 ATPs. Those from FADH2 have only enough for 2 ATPs."Spent" hydrogens combine with oxygen
26. What is the fate of electron in the ETC?
NADH and FADH2 pass their high-energy electrons to the Electron Transport Chain
27. What substance is found at the end of the ETC that accepts an electron?
Oxygen
28. What facilitates the reaction in the ATP synthase complex?
1. Complex 1/NADH
2. Complex 2/succinate
29. What is the final fate of the electron in the ETC? (ie, final product)
Oxidized NADH + H+ and FADH2 are "substrates" used
• Yields 2.5 ATP per NADH and/or 1.5 ATP per FADH
• The end product is H2O - oxygen final electron acceptor
30. What is the final fate of H+ in the ETC? (ie, final product)
The H+ falling through the ATP synthase provides the energy for the ATP synthase to catalyze the reaction of ADP + P →ATP
