Question

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. For each part, select all that apply.
(a) Which compounds donate electrons to the electron transport chain?
1. H2O
2. NADH
3. NAD+
4. ATP
5. ADP
6. O2
7. FADH2
8. FAD
(b) Which of the following is the final electron acceptor?
1. H2O
2. NADH
3. NAD+
4. ATP
5. ADP
6. O2
7. FADH2
8. FAD
(c) Which of the following are the final products of the electron transport chain and oxidative phosphorylation?
1. H2O
2. NADH
3. NAD+
4. ATP
5. ADP
6. O2
7. FADH2
8. FAD

Answer 1

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The answers are as;

a) 1. NADH and 7. FADH2

b) 6. O2

c) 3. NAD+, 1. H2O, 4. ATP and 8. FAD

Oxygen is the ultimate electron acceptor, and it combines with hydrogen ions to produce H2O. This process occurs at the conclusion of the electron transport process.

ATP molecules, which are carriers of energy, would be the final outcome of the oxidative phosphorylation process.

(a) NADH and FADH2 donate electrons to the electron transport chain.

(b) O2 is the final electron acceptor.

(c)  NAD+,  H2O,  ATP, and  FAD are the final products of the electron transport chain and oxidative phosphorylation.
