2. oxidative phosphorylation
3. glycolysis and fermentation
4. reduction of
1. the citric acid cycle
2. oxidative phosphorylation
3. glycolysis and fermentation
4. reduction of
The number of oxygen molecules required each time a molecule of glucose is completely oxidized via aerobic respiration is:
| 1. | 1 | 2. | 2 |
| 3. | 6 | 4. | 12 |
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 |
Identify the incorrectly matched pair:
| Component of ETC | Name | |
| 1. | Complex I | NADH dehydrogenase |
| 2. | Complex II | Succinate dehydrogenase |
| 3. | Complex III | Cytochrome b6f complex |
| 4. | Complex IV | Cytochrome c oxidase |
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 |
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
A multienzyme complex amongst the following would be:
| 1. | sucrase |
| 2. | |
| 3. | hexokinase |
| 4. | pyruvate dehydrogenase |
To generate a proton gradient, in mitochondria, the protons are pumped:
| 1. | into the cytosol from the mitochondria |
| 2. | from the mitochondrial matrix into the intermembrane space of the mitochondria |
| 3. | from the cytosol into the matrix of the mitochondria |
| 4. | out of the nucleus and into the mitochondria |
