Q. No.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 |
The pathway that normally occurs whether or not oxygen is present would be would be:
I. glycolysis
II. fermentation
III. citric acid cycle
1. Only I
2. I and II only
3. II only
4. III only
