In glycolysis:
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
| I: | ATP is utilised at two steps: first in the conversion of glucose into glucose 6-phosphate and second in the conversion of fructose 6-phosphate to fructose 1, 6-bisphosphate. |
| II: | ATP is produced at two steps: first in the conversion of BPGA to 3-phosphoglyceric acid (PGA), and second during the conversion of PEP to pyruvic acid. |
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect

The step in the glycolytic pathway where NADH + H+ is formed from NAD+ is when:
| 1. | fructose 1, 6-bisphosphate is split into dihydroxyacetone phosphate and 3-phosphoglyceraldehyde (PGAL) |
| 2. | 3-phosphoglyceraldehyde (PGAL) is converted to 1, 3-bisphosphoglycerate (BPGA) |
| 3. | BPGA is converted to 3-phosphoglyceric acid (PGA) |
| 4. | PEP is converted to pyruvic acid |

Consider the given two statements:
1. Statement I is correct; Statement II is correct
2. Statement I is incorrect; Statement II is correct
3. Statement I is correct; Statement II is incorrect
4. Statement I is incorrect; Statement II is incorrect
| Statement I: | ATP formation by glycolysis requires oxygen |
| Statement II: | ATP can be formed through substrate-level phosphorylation and this process requires a high-energy phosphate group that is transferred directly to ADP. |
