Q. No.Glucose fermentation by Yeast yields:
1. Ethanol + CO2
2. Ethanol + H2O
3. Methanol + CO2
4. H2O + CO2
During fermentation by Yeast, Alcohol is formed from:
1. Proteins
2. Sugars
3. Muco-polysaccharides
4. Fats
Consider the following two statements:
| Statement I : | Fermentation serves an important purpose in muscle cells during exercise. |
| Statement II : | It is the only mechanism of ATP production under such conditions. |
| 1. | Both Statement I and Statement II are correct and Statement II explains Statement I |
| 2. | Both Statement I and Statement II are correct but Statement II does not explain Statement I |
| 3. | Statement I is correct but Statement II is incorrect |
| 4. | Both Statement I and Statement II are incorrect |
In aerobic cellular respiration, oxygen is actually directly used only by:
1. Glycolysis
2. Oxidation of pyruvate
3. Kreb’s cycle
4. Electron transport
What percent of ATP produced during glycolysis are the result of substrate level phosphorylation?
1. 0
2. 25
3. 50
4. 100
Pyruvate enters the mitochondrion by:
1. Active transport
2. Facilitated diffusion
3. Diffusion
4. Through a channel
In β-oxidation:
| 1. | Fatty acids are joined to form acetyl CoA |
| 2. | Fatty acids are broken down to form Acetyl CoA |
| 3. | Amino acids are converted to glucose |
| 4. | Amino acids are converted to intermediates of Kreb’s cycle |
The products of three turns of Kreb’s cycle will be:
1. 1 ATP, 2 CO2, 3 NADH, and 1 FADH2
2. 3 ATP, 3 CO2, 3 NADH, and 3 FADH2
3. 3 ATP, 6 CO2, 9 NADH, and 3 FADH2
4. 38 ATP, 6 CO2, 3 NADH, and 12 FADH2
The mitochondrial electron transport chain is located in:
1. The outer membrane
2. The inner membrane
3. The inter-membrane space
4. Stroma
