Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R):
In the light of the above statements, choose the correct answer from the options given below :
| Assertion (A): | ATP is used at two steps in glycolysis . |
| Reason (R): | First ATP is used in converting glucose into glocose-6-phosphate and second ATP is used in conversion of fructose-6-phosphate into fructose-1-6-diphosphate. |
In the light of the above statements, choose the correct answer from the options given below :
| 1. | (A) is False but (R) is True. |
| 2. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 3. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 4. | (A) is True but (R) is False. |

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 |
