By the end of glycolysis, most of the original energy in the glucose molecule is:
1. utilized to form ATP.
2. retained in the pyruvate.
3. stored in the NADH produced.
4. lost as heat.
The number of molecules of carbon dioxide produced by three turns of the Krebs cycle would be:
1. | 3 | 2. | 6 |
3. | 12 | 4. | 18 |
What is the total number of NADH and molecules produced for each molecule of glucose metabolized by glycolysis and the citric acid cycle?
1. | 5 | 2. | 6 |
3. | 10 | 4. | 12 |

The correct sequence of electron flow during aerobic respiration would be:
1. food → Krebs cycle → ATP → NAD+
2. food → NADH → electron transport chain → oxygen
3. glucose → pyruvate → ATP → oxygen
4. glucose → ATP → electron transport chain → NADH
Electron is donated to the mitochondrial ETC at the lowest energy level by:
1. | Glucose | 2. | NADH |
3. | ATP | 4. | FADH2 |
When electron pass downhill in the ETC, the energy released is used to pump protons into:
1. matrix of mitochondria
2. cytosol
3. mitochondrial inner membrane
4. mitochondrial intermembrane space
ATP synthesis during oxidative phosphorylation in mitochondria is directly driven by:
1. oxidation of glucose.
2. electron transport downhill in the ETC.
3. terminal transfer of electrons to oxygen.
4. chemiosmosis.

Let us say there are 30 NADH and 12 in a mitochondrion. What is the maximum number of ATP generated if all dinucleotides are used in chemiosmosis?
1. | 42 | 2. | 84 |
3. | 114 | 4. | 142 |
The correct chronological sequence of the stages of the glycolytic pathway is:
1. | glucose priming, cleavage and rearrangement, oxidation, ATP generation |
2. | cleavage and rearrangement, glucose priming, ATP generation, oxidation |
3. | glucose priming, oxidation, cleavage and rearrangement, ATP generation |
4. | ATP generation, oxidation, glucose priming, cleavage and rearrangement |
