When an electron is shifted to a more electronegative atom, its potential energy:
1. | increases | 2. | decreases |
3. | remains same | 4. | can increase or decrease |
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.

Chemiosmosis is coupled to energy storage by:
1. | NADH | 2. | ADP |
3. | cytochromes | 4. | ATP synthase |
Ubiquinone is:
1. a protein in the mitochondrial electron transport chain
2. a substrate for synthesis of FADH
3. a vitamin used as coenzyme in Krebs cycle
4. a small hydrophobic coenzyme
All the following will normally occur during the electron flow in ETS in mitochondria except:
1. NADH and are oxidized.
2. the pH of the matrix decreases.
3. the electrons lose free energy.
4. an electrochemical gradient is formed.
Direct use of oxygen is in:
1. | Glycolysis | 2. | Fermentation |
3. | Krebs cycle | 4. | Electron transport |
