Q. No.In the glycolytic pathway, ATP formation:
1. does not occur
2. requires presence of oxygen
3. needs a proton gradient across a membrane
4. involves substrate-level phosphorylation

3. needs a proton gradient across a membrane
4. involves substrate-level phosphorylation
In the ETS in mitochondria, identify the product that is not correctly matched with its number:
| 1. | NAD+ = 10 | 2. | FAD = 2 |
| 3. | ATP = 26 | 4. | H2O = 12 |
Maximum energy can be released during the oxidation of:
| 1. | proteins | 2. | glucose |
| 3. | fatty acids | 4. | nucleic acids |
The glycolytic pathway occurs in:
1. cytoplasm
2. chloroplasts
3. matrix of the mitochondrion
4. cristae of the mitochondrion
In lactate fermentation, the final electron acceptor is:
| 1. | NAD+ | 2. | pyruvate |
| 3. | O2 | 4. | lactic acid |
Coenzyme A, formed in part from one of the B vitamins, functions to:
| 1. | Oxidize pyruvate | 2. | Reduce pyruvate |
| 3. | Activate the acetyl group | 4. | Facilitate electron flow |
Yeast cells are able to regenerate regenerated from NADH during the :
1. reduction of acetaldehyde to ethyl alcohol
2. oxidation of pyruvate to acetyl CoA
3. reduction of pyruvate to form lactate
4. oxidation of NAD+ in the citric acid cycle
Fats and proteins can also provide us energy. For this to happen:
| 1. | Fats and proteins must first be converted to glucose |
| 2. | Fats and proteins must enter separate catabolic pathways of their own |
| 3. | Fats and proteins must be modified to forms that can enter the glucose metabolic pathway |
| 4. | Fats must first be converted to proteins that can enter the glucose metabolic pathway |
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. |
