A reducing agent in a redox reaction:
1. gains electrons and gains energy.
2. loses electrons and loses energy.
3. gains electrons and loses energy.
4. loses electrons and gains energy.
By the end of glycolysis, most of the original energy in the glucose molecule is:
1. utilized to form ATP.
2. retained in the pyruvate.
3. stored in the NADH produced.
4. lost as heat.
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

The processes that occur in the cytosol of a eukaryotic cell is/are:
I. glycolysis
II. fermentation
III. oxidation of pyruvate to acetyl CoA
| 1. | Only I | 2. | I and II only |
| 3. | I and III only | 4. | I, II, III and IV |
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
The glycolytic pathway occurs in:
1. cytoplasm
2. chloroplasts
3. matrix of the mitochondrion
4. cristae of the mitochondrion
