| 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. |
| I: | It occurs in the matrix of mitochondria. |
| II: | It links glycolysis to the Krebs cycle. |
| III: | Two oxygen molecules are given off from glucose. |
| IV: | Four NADH molecules are formed from the reaction. |
| A: | ER |
| B: | Golgi apparatus |
| C: | Mitochondria |
| D: | Chloroplasts |
| I: | \(\mathrm{C_6H_{12}O_6} → 2~ \text {pyruate} + \text{X} \text {ATP}\) |
| II: | \(\mathrm{C_6H_{12}O_6} → 2~ \text {lactate} + \mathrm{X} \text {ATP}\) |
| III: | \(\mathrm{C_6H_{12}O_6} → 2~ \text {alcohol} + 2 \mathrm{CO_2}+\mathrm{X} \text {ATP}\) |
| 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. |
