The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The energy from the electron transport chain is used for oxidative phosphorylation.

a)Which compounds donate electrons to the electron transport chain?
b)Which of the following is the final electron acceptor?
c) Which of the following are the final products of the electron transport chain and oxidative phosphorylation?

Answer choices for a), b), and c) (maybe used more than once)
1. H20
2. NADH
3. NAD+
4. ATP
5. ADP
6. O2
7. FADH2
8. FAD

a. NADH, FADH2

b O2

c. ATP, H2O

Explanation:

The reduced coenzyme that is generated in the citric acid cycles are NADH and FADH2. These coenzymes feed electrons in the electron transport chain which moves through electron acceptors present in the ETC.

The final electron acceptor in the electron transport chains is oxygen which converts into H2O. This movement of electron through ETS allows the movement of H+ ions from the mitochondrial matrix to intermembrane space.  

These H+ ions when it comes back in the matrix through ATP synthase it generates ATP. So ATP and H2O are the final products of ETC and oxidative phosphorylation.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

that's what i got you can count the number of atoms
