What would be true when comparing the processes of anaerobic respiration and fermentation?
I. | Both processes do not use oxygen. |
II. | An electron transport chain is used in anaerobic respiration but not in fermentation. |
1. | Only I | 2. | Only II |
3. | Neither I nor II | 4. | Both I and II |
When oxygen is not available to a cell, NADH formed during glycolysis:
1. | does not undergo any change as there is no need for the cell to regenerate NAD+ |
2. | passes electrons to the electron transport system |
3. | passes hydrogen atoms to pyruvic acid |
4. | passes electrons and hydrogen atoms to acetyl coA |
Assertion (A): | Fermentation is a type of anaerobic respiration where glucose is partially oxidized to produce energy. |
Reason (R): | Fermentation results in the production of ethanol or lactic acid without the use of oxygen. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | Both (A) and (R) are True but (R) does not correctly explain (A). |
3. | (A) is True, (R) is False. |
4. | Both (A) and (R) are False. |
I: | less than 7 percent of energy in glucose is released. |
II: | all energy released is trapped as high energy bonds of ATP. |
